嗨。

Hi.

我是林赛。

I'm Lindsey.

我是马歇尔。

And I'm Marshall.

欢迎收听《Tumble》，一档探索科学发现故事的节目。

Welcome to Tumble, the show where we explore stories of science discovery.

今天这期是《Tumble》的‘挠痒痒来信特辑’。

Today, we have a tickle attack mailbag edition of Tumble.

我们要来回答大家关于动物会不会怕痒的问题。

We're tackling your tickling questions about whether or not animals can be tickled.

我们肯定会从最近听众的来信和评论里找到不少笑点。

And we are sure to be tickled by our most recent round of listener mail and comments.

好嘞。

Okay.

所以马歇尔，你怕痒吗？

So Marshall, are you ticklish?

说实话，其实我不怎么怕痒。

I mean, actually, to tell the truth, not really.

没那么敏感，其实这样挺好的。

Not that much, which is actually really great.

这可是个绝妙的武器，我能用它去逗别人，自己却不会被挠到。

It's a wonderful weapon because then I can wield it but not be harmed by it.

对。

Yes.

我见过你变成一个超级可怕的挠痒怪。

I have seen you transform into a very dangerous tickle monster.

没错。

Indeed.

小心点啊。

Beware.

我们马上就会聊那些挠痒的问题。

We're gonna get to those tickle questions soon.

不过在那之前，先来看看听众来信吧。

But first, let's start with our listener mail.

好，

Alright.

咱们先来看看苹果上的用户评价。

Let's start off with our Apple reviews.

好，

Alright.

我能

Can I

念一下这个吗？

read this one?

对。

Yeah.

上面写着：再也没那些坏猫了。

It says no more evil cats.

还给了我们五星好评。

It gives us a five star review.

谢谢。

Thank you.

谢谢你，猫奴。

You very much, the cat person.

他说，你们说猫是邪恶的，我有点不高兴。

It says, I am a bit offended that you said cats are evil.

好吧。

Okay.

其实我还不只是有点不高兴——我家猫正蹲在按摩椅上，把你们说的话一字不落全听进去了。

More than a bit offended, I also have a cat who's above the massage chair listening to every word you say.

所以下次说话，可得注意点，别乱黑猫。

So next time, be aware of what you say about cats.

我超爱这猫蹲在按摩椅上的画面。

I love that the cat's above a massage chair.

它就等着呢。

It's just waiting.

你躺在按摩椅上还挺舒服的嘛

Like, you're comfortable in that massage

你正放松着呢

You're relaxing.

你享受着按摩，猫就在上面听着你的播客，静静等着呢

You're enjoying a massage, and the cat is just listening to your podcast, waiting.

等着找机会下手呢

Waiting for the moment to strike.

我得说，这可不像是在证明那只猫不坏啊

I have to say, that's not a strong advertisement that that animal is not evil.

确实不是

No.

完全不是

It's not.

行吧

Alright.

我真的很看重这个评价。

I still appreciate that review a lot.

我还是会超爱它那副坏猫咪的表情。

I'd still probably love its evil kitty face.

是的。

Yeah.

好。

Okay.

这个我要说，我超爱《Tumble》。

This one is I love Tumble.

嗨，林赛和马歇尔。

Hi, Lindsey and Marshall.

我真的特别喜欢《Tumble》。

I absolutely love Tumble.

麻烦在下一期邮件问答和点评环节里读一下我的评论。

Please read my review in the next mailbag and review read episode.

附带一提，我不确定你们有没有做过，但能不能做个节目讲讲，为啥从泳池出来后手会皱得像葡萄干？

PS, I don't know if you made one yet, but can you make an episode about why does our hands look like raisins after coming out from a swimming pool?

谢谢，这是Rachel寄来的。

Thank you, from Rachel.

是的。

Yeah.

这还真是个挺棒的节目选题。

That's that's actually a great topic for an episode.

咱们真该做个邮件问答专场，就讲这个。

We should we should do, like, we should do a mailbag episode on that.

我其实特别好奇。

Because I'm actually really curious.

你看葡萄干是干瘪的，可你刚从水里出来，明明是泡得水汪汪的啊。

Because it seems like like raisins are all dried out, but you've been in the pool.

你这情况跟干瘪完全相反。

You're the opposite of dried out.

那这到底是怎么回事呢？

So what's what's going on there?

这真让人想不通。

It's a mind bender.

当然啦，我们看了你的评论，刚看的。

And yes, we will read your review, and we just did.

好的。

Alright.

下一个评论太棒了，还给我发了七个笑眯眯、星星眼的emoji，五星好评。

So this next one is this is so good, and then gives me seven smiling, starry eyed emojis, and it's a five star review.

谢谢。

Thank you.

真的太感谢了。

Thank you.

我超爱科学。

I love science.

我也是。

Hey, me too.

大部分科学类播客要么太浅显，要么太深奥。

And most science podcasts are, like, so simple or so deep.

但我想要一个既能让我觉得有趣，又可以一边听一边走神的科学播客。

But I want a science podcast that I can listen to and think that it is interesting, but also I can kinda like zone out.

这个正好就完美了。

So this is like perfect.

对了，你们可以做个关于酒精科学的专题。

Anyway, I think you should do one on the science of alcohol.

我觉得这个主题特别棒。

Oh, I think that would be a great episode.

拜拜。

Bye.

我也不太确定。

I don't know.

我们真会做一期关于酒精的科学吗？

Would we ever do the science of alcohol?

说真的，酒精的科学到底指的是啥？

Like, what is the science of alcohol?

我琢磨着，其实讲的是发酵的科学。

I was thinking it's like the science of fermentation.

这里面有挺多分子层面的东西。

There's like a molecular element to it.

不过我们也收到不少问题，问酒精对人体有什么影响。

But we have received other questions about what alcohol does to people.

所以我们得再收到些更具体的问题，才能知道该怎么展开。

And so we just need more specific questions so we can kinda know how to handle it.

行吧。

Alright.

关于苹果的评价就这些了。

That's it for Apple reviews.

接下来咱们看啥？

What do we have next?

好。

Okay.

接下来是Spotify的评论。

Up next, we've got Spotify comments.

我们特别喜欢看Spotify上对节目的评论，尤其是那个《我的世界》实验，评论最多，还有一条纠正《我的世界》内容的。

We do love reading comments on episodes on Spotify, and the Minecraft experiment got the most comments, including a Minecraft correction.

明白。

Alright.

那我来念一条。

So I'll read this one.

行。

Sure.

Sergio seven US 在《我的世界》实验那期下面留言说：我七岁。

Sergio seven US commented on the Minecraft experiment saying, I am seven.

这太有意思了，因为我超爱打游戏。

This is so interesting because I love gaming.

你说的是猪人，但猪人其实是游戏里的正式角色。

And you said pigmen, but pigmen are real characters in a game.

哦，是这样啊。

Okay.

所以不是叫猪人吗？

So it's not pigmen?

我一直以为就叫猪人呢。

I always assumed it was pigmen.

它们长得跟猪一样。

They look like pigs.

真长得像猪？

Do they look like pigs?

对啊。

Yeah.

电影里是这么演的。

In the movie, they did.

大概是吧。

I guess.

不过下一条评论里有人指出，我居然只靠《我的世界》这部电影当依据。

But I've been sort of called out for my only source being the Minecraft movie in this next comment.

嗯，知道了。

Okay.

行吧。

Alright.

Luca 和 Ariel，还是个新号，说：第一，别信《我的世界》这部电影。

Luca and Ariel, still just a new account, say, one, do not trust the Minecraft movie.

那肯定是骗人的，我想。

It is lies, I guess.

还有，别忽视英雄 Brian，不然你的我的世界存档会被删掉。

Also, do not ignore hero Brian or your Minecraft world will be deleted.

你的账号会被删掉。

Your account will be deleted.

连你的电脑都可能被删。

Your computer will be deleted even.

而且还是全大写的。

And that's all in caps.

好吧。

Okay.

我对Minecraft了解不多，没法判断这到底是真是假。

I do not know enough about Minecraft to say whether I think that's true or false.

我根本不知道Herobrine是什么。

I don't know what Herobrine is.

我也不知道该怎么‘忽略’它或者‘注意’它。

I don't know how one ignores it or pays attention to it.

你到底对Herobrine干了啥？

What Like, are you doing to Herobrine?

好的。

Okay.

我听了Unspookable上一期关于Herobrine的节目，那是个特别棒的播客，强烈推荐你去听听，能让你真正了解Herobrine。

I listened to an episode about Herobrine on Unspookable, another great podcast, and I really recommend that to get informed about Herobrine.

好。

Okay.

我去看看。

I'll I'll check it out.

给Unspookable点个赞。

Shout out to unspookable.

对。

Yes.

好的。

Okay.

我们还有一个叫David Roberts的听众，在好多期节目底下都留言了，我最喜欢他关于蜘蛛歌曲的那段评论。

So we also had a commenter named David Roberts commented on a lot of the episodes, and here was my favorite about the songs of spiders.

我卖家那儿有只蜘蛛，我管它叫戴夫蜘蛛。

There's a there's a spider on my selling, and I naming him Dave Spider.

戴夫啊，你可得乖点。

Dave, you better behave.

P.S. 把这个编成首歌吧。

PS, make this a song.

马歇尔，真的真的太感谢你了。

Marshall, please, please, and thank you.

表情包走起。

Emojis.

大卫·罗伯茨，你想要的，这就给你安排上。

Well, David Roberts, ask and ye shall receive.

你的请求，我答应了。

I am granting your request.

来，这首曲子我真挺自豪的。

Here is I'm actually really proud of this song.

哦，蜘蛛戴夫。

Oh, Spider Dave.

行吧。

Alright.

我太兴奋了。

I'm so excited.

你确实该这么兴奋。

As well you should be.

就是蜘蛛戴夫。

Him Spider Dave.

他就是个普通的家蛛，才几毫米长。

He's just a common house spider, only a few millimeters in length.

他吃虫子，所以让他待在这儿吧。

He eats bugs, so he can stay here.

至少我是这么想的。

At least that's what I think.

但到了晚上，我上床睡觉的时候，

But at night, when I go to bed,

我就会来这么一段，

I have this

唱首歌给他听。

song to sing.

哦，蜘蛛戴夫，你可得规矩点。

Oh, Spider day, you better behave.

别爬到我床上来啊。

Don't crawl on my bed now.

别跳到我脸上。

Don't jump on my face.

咱俩都心知肚明，得讲点规矩。

I'm sure you can see that we both must agree.

你要是敢爬我床，那就别怪我不客气，赶紧滚蛋。

Don't crawl on my bed now or else you must leave.

现在呢，这只蜘蛛在我

Now now this spider on my

天花板上爬来爬去的。

ceiling, he walks and crawls about.

它织了一堆乱七八糟的网，可从不吵不闹。

He makes a messy cobweb, and he never makes a shout.

但每到晚上，我快睡着的时候还是挺担心的。

But still at night, I'm worried as I'm about to go to sleep.

它到底听没听进我的话啊？

Did he listen to my pleas now?

我们都明白，

And knew we both agree that,

哦，蜘蛛啊，你可得规矩点。

oh, spider day, you better behave.

别爬到我床上来。

Don't crawl on my bed now.

别跳到我脸上来。

Don't jump on my face.

我相信你我也都心知肚明。

I'm sure you can see that we both must agree.

你要是再敢爬我床上，就赶紧滚蛋。

Don't crawl on my bed now or else you must leave.

别再鬼鬼祟祟地乱爬了。

Now stop creeping about.

你最好马上走人。

You better get out.

你都爬到我床上来了。

You crawled on my bed now.

你居然跳进我嘴里了。

You jumped in my mouth.

你最好

You better

你真的在那首歌结尾时吃了一只蜘蛛？

actually eat a spider over the end of that song?

这事我不能说。

I will not disclose that fact.

别说了。

Leave it

留点想象空间吧。

to your imagination.

太牛了。

It was incredible.

我觉得这可能是史上唯一一首回应Spotify评论的歌了。

I think that might be the only song ever made in response to a Spotify comment Yeah.

还是个儿童播客里的歌。

On a children's podcast.

说不定吧。

Maybe.

我也不知道。

I don't know.

或者说是第一个这么做的。

Or the first ever.

这说不定会成一股风潮。

This could be a trend.

行吧。

Okay.

好了，评论的事就聊到这儿。

Well, so that does it for comments.

我们特别喜欢听大家的评论，每一条都会看，只是不一定在节目里念出来。

We do love getting comments and we do read them all even if we don't read them on the show.

所以欢迎大家留言，要是想让我们在节目里回答问题，就发邮件到 tumblepodcast@gmailcom 吧。

So please leave comments and if you want a question on the show, go ahead and send it to us via email at tumblepodcast@gmailcom.

好的。

Alright.

我们先歇一小会儿，回来之后聊聊几个挺有意思的问题。

We're gonna take a quick break, and when we come back, we'll tackle some tickling questions.

《Tumble》由IXL Learning赞助播出。

Tumble is brought to you with support from IXL Learning.

好的。

Okay.

我们回来了。

We're back.

从Tumble开播以来，只要一收听众来信，就总有人问关于挠痒痒的问题。

So since almost the beginning of Tumble when we started taking listener questions, we've gotten questions about tickling.

我是说，挠痒痒这事儿真挺让人好奇的。

I mean, I think tickling is a very curious subject.

对啊。

Yeah.

你被挠痒的时候，心里不就纳闷吗：这怎么就发生了呢？

It's like when you're being tickled, you're like, why is this happening?

我记得我第一次知道猿类也会怕痒的时候。

I I know the moment when I learned that apes are ticklish.

那一刻，猿类彻底改变了我的人生。

All apes changed my life.

没错。

Yes.

从那以后，你就完全不一样了。

You've been a different person since then.

总有一天，我要去挠一只小黑猩猩的痒痒。

Someday, I'll I'll get to tickle a baby chimpanzee.

那也太棒了吧。

That would be amazing.

说来也巧，我请来回答听众关于挠痒问题的那个人，以前的工作就是去挠猩猩痒。

Well, it's funny you should mention that because the person that I have lined up to answer our listener's tickling question actually had a job where he tickled a chimp.

等等。

Wait.

还有专门挠猩猩痒的职业？

So there are professional chimp ticklers?

这事儿说不定真是工作内容之一。

It's part could be part of a job description.

是工作内容的一部分，还是全部？

Is it part, but the whole thing?

我放一段录音给你听。

Let me play you this clip.

我可以放吗？

Can I do that?

是的。

Yeah.

克林特是个特别特别可爱的黑猩猩。

Clint was just a lovely, lovely, lovely chimpanzee.

每次见到我都很开心。

Always happy to see me.

我们俩经常趁上班的空儿，玩上半天，包括互相挠痒痒。

We used to used to just spend half the time where we're supposed to be working, playing together, including tickling.

他特别喜欢被人挠痒痒。

He loved to be tickled.

他会往后退，指着自己最想被挠的地方，还反过来挠我。

He'd back up, show me right where he wanted to be tickled, and he tickled me back.

千万别让黑猩猩给你挠痒痒。

Don't ever let a chimpanzee tickle you.

它们挠得怎么样？

Are they good ticklers?

是的。

Yes.

天哪。

Oh my god.

没错。

Yes.

你看，这恰恰说明让黑猩猩挠你挺好的。

See, I think that's an argument for letting a chimpanzee tickle you.

我不是说，它们挠得也太狠了吧？都快把你命给挠没了？

I don't like, do they tickle you so hard that you like, your life is in danger?

就是笑得停不下来，会不会憋得喘不上气？

Like, you're laughing so much, like, maybe you'll suffocate?

那是戴夫·利文斯。

Well, that was Dave Leavens.

他是个心理学家，专门研究挠痒痒的。

He is a psychologist and an expert on tickling.

我觉得他最适合回答孩子们的问题了。

I thought that he would be the perfect person to answer our kids' questions.

明白了。

Okay.

那听众们最想了解关于挠痒痒的什么问题呢？

Well, so what do listeners wanna know about tickling?

咱们先来看看莉莉、利亚姆和布罗迪·G发来的邮件里提的问题。

Well, let's start this question that we got in an email from Lily, Liam, and Brody G.

他们问：为什么人会被挠痒痒，狗却不会？

Their question is, why can humans be tickled, but dogs can't?

我们超爱你们的播客。

We love your podcast.

谢谢啊，各位。

Thanks, guys.

为什么人会被挠痒痒，狗却不会？

Why can humans be tickled but dogs can't?

我想狗应该不会怕痒吧。

I I guess dogs aren't ticklish.

我以前还真没想过，但好像确实不会。

I never really thought about it, but I guess they're not.

马歇尔，你可就猜错了。

Well, Marshall, you'll be wrong.

这是戴夫告诉我的。

This is what Dave told me.

其实狗是怕痒的。

Dogs, evidently dogs are ticklish.

它们并不是对挠痒完全没反应。

They're not universally insensitive to tickling.

只是表现方式不一样。

They show it differently.

它们不会像人那样哈哈大笑。

They don't don't guffaw.

简单说，你轻轻摸他们的肋骨，那条腿就会不自觉地抖动，这大概就是他们的痒痒反应。

Basically, you start probing gently along their along their flanks and they that that leg starts jerking up and down, probably that that's their tickle response.

等等。

Wait.

所以这是他们在怕痒？

So that's them being tickled?

我一直以为那是……天啊，太舒服了。

I I always thought that was just like, oh my god.

那种感觉真的太棒了。

That feels so amazing.

你真是再合适不过了。

You're the perfect person.

我一直以为那就是这个意思。

That's what I thought that meant.

哦。

Oh

我的天啊。

my gosh.

这下清楚了吧。

Well, there we go.

看来我之前想错了。

I guess I was wrong.

狗确实怕痒。

Dogs are ticklish.

只是它们的反应不像我们想象的那样明显。

They just don't laugh in a way that we notice.

它们可不会哈哈大笑。

They do not guffaw.

确实不会哈哈大笑，至少在人面前不会。

They do not guffaw, or at least not when humans are listening.

明白了。

Okay.

还有个关于动物痒痒的问题是Penny问的：除了人类，其他动物也会怕痒吗？

So we got another question about animal tickles from Penny, who asks, are other animals besides humans ticklish?

如果会的话，它们会玩挠痒痒比赛吗？

And if they are, do they have tickle fights?

咱们已经知道狗会怕痒了，那还有哪些动物呢？

Well, I guess we already know dogs, but what else?

其实很多动物被挠的时候都会发出类似笑声的声音。

Well, a lot of animals will laugh or engage in something like laughing behavior when you tickle them.

说起来，好多小动物好像都挺享受被人挠痒痒的。

Turns out, you know, lots of critters seem to enjoy being tickled.

让我觉得奇怪的是，真正会去挠别人痒痒的动物其实很少。

The curious thing to me is that there there are relatively few animals that actually tickle others.

但人类会挠别人痒，大猿类也会——毕竟它们是人类最近的近亲。

But people tickle others and great apes tickle others, humans nearest living relatives.

动物之间互相挠痒痒，这事儿可不多见。

It's a rare thing for for for animals to tickle each other.

但类人猿不一样，你把一只小幼崽放到它们身边，它们就会立刻开始挠小家伙痒痒。

But great apes, well, know, you you put them around an infant and and they'll start tickling away.

而且它们既喜欢挠别人痒痒，也喜欢被别人挠。

And, you know, they they like to tickle and they like to be tickled.

同时具备这两种特点的动物其实非常少见。

That pairing is unusual.

原来是这样。

Alright.

那这么说，除了我们人类之外，整个动物界里也就只有类人猿会主动去挠别人痒痒了

So it's the great apes who were the best ticklers in the animal kingdom next

没错

to us.

感觉好像就只有这俩会互相挠痒痒似的

Sounds like they're the only ticklers.

对的

Yeah.

最棒的，也是唯一的。

Best and only.

那在人类出现之前，狗是怎么学会怕痒的呢？那时候根本没人去挠它们啊。

And so how did dogs learn that they were ticklish if nothing was tickling them before humans showed up?

它们以前可是狼啊，在人类出现之前。

Well, they were wolves before humans showed up.

对吧？

Right?

我想是吧。

I guess.

狼怕痒吗？还是说这事儿太危险，根本没法去验证？

Are wolves ticklish, or is that too dangerous to find out?

我可不打算报名参加这种挠狼研究。

I wouldn't sign ourselves up for that tickle study.

对。

Yeah.

别跟危险的食肉动物玩挠痒痒大战。

No tickle fights with dangerous carnivores.

但戴夫确实说过，如果有人想研究各种动物的痒感反应，这领域大有可为。

But Dave does say that there is a real potential for somebody who wants to study tickling across all types of animals.

是啊。

Yeah.

我跟你说真的。

I'm telling you.

这可是个完全空白的研究领域。

It's a wide open area for study.

我要是刚起步，绝对会把这当成能彻底改变科学界的绝佳方向。

If I was starting my career, I would see this as a completely viable way to really make a mark on science.

根本没人系统地去查哪些动物喜欢被挠痒痒。

There's nobody out there, you know, who is systematically going through and and and seeing which animals like to be tickled.

我们对这方面的无知，连自己不知道啥都不知道。

What we don't know about this area we don't even know what we don't know.

有人完全可以靠研究动物的痒感反应来当一辈子专家。

Somebody could make a career out of just being a comparative tickalogist.

这工作真够神奇的，动物痒感比较学家。

That's kind of an amazing job, a comparative tickalogist.

所以啊，孩子们要是想长大当科学家——我希望现在听节目的人里至少有一部分是这样想的——不如就研究痒感吧。

So you hear that kids who wanna be scientists when you grow up, which I hope is at least some of the people listening right now, tickling.

你就能成为世界闻名的先驱、全球顶尖的痒感研究大牛。

You could be a world famous pioneer, world expert tickle studier.

痒学专家。

Tickleologist.

你就一个个动物研究下去，看它们被挠时的反应，当然得从蠕虫开始。

And you just study each animal and how it responds to tickling, and you would, of course, start with worms.

一路往上研究。

All the way up.

一路往上研究。

All the way up.

好的。

Okay.

这是里德和西奇提出的一个问题。

So here is a question from Reed and Sage.

为什么我们被挠痒痒的时候会笑？

Why do we laugh when we get tickled?

挠痒痒之所以有效，其中一个原因就是那种突如其来的意外感——你根本猜不到下一步会发生什么。

One of the ways that that tickling sort of works, is is this surprise factor, this this inability to anticipate, what's gonna happen next.

比如你正在野餐，突然感觉有东西在身上爬，你肯定会吓一跳。

If you're sitting around at a picnic and you feel something crawling on you, you know, you'll jump.

这种突如其来的惊吓反应，很多人都有。

You know, you get a real startle response from that sort of a thing.

其他动物也一样，它们能立刻意识到：这不是我自己弄出来的。

And other other animals had that same sort of immediate recognition that this isn't caused by me.

很多动物都觉得挠痒痒很舒服，可它们自己却不会去挠别的动物，这或许能帮我们换个角度理解‘自我’——一种基于触觉的自我认知。

The fact that so many animals seem to find tickling pleasurable, even though they themselves don't tickle others, might present an avenue for for a different way of thinking about a sense of self, you know, one that's based in touch.

那他这到底在说啥？

So what what what is he talking about here?

意思是，被挠痒痒能定义我们的自我？

Like, tickling defines our sense of self?

是的。

Yeah.

就是‘自我’这个概念。

It's like the idea of self.

你咋知道自己是谁，又咋知道自己不是别人或别的东西。

How you know who you are and how you know that you're not someone or something else.

是什么让你跟这个世界区分开来的？

What defines you from the rest of the world?

嗯，明白了。

Okay.

可这跟挠痒痒有啥关系？

But what does that have to do with tickling?
