- (Katie) All right. So today you're gonna be watching
a series of videos. - (whimpers)
(laughs) I'm always a little trepidatious.
- (Katie) And the challenge is
you cannot smile or laugh while watching. - Nooo! Why?!
- NO WAY!! I've always wanted to do this! Whoa.
- (Katie) The videos have been sent in by fans
who think they can get you to laugh or smile.
- It'll be tough, but I think I can beat you.
- Good luck.
- Hey, people. Make sure it's funny,
because if it's not, you're not winning.
- Let me put my serious face.
- (blows) I got this.
- This is the science of laughter. So let's laugh with Yogi, huh?
Ha ha ha ha ha ha ha ha ha ha.
So first, breathe and then laugh. So just laugh anytime.
(rhythmically) Ha-ha, ha-ha, ha-ha, ha-ha, ha-ha.
- Nope.
(Yogi giggles annoyingly)
- (busts out laughing)
That is so stupid!
(buzzer)
- (Yogi) Eeeeeeeeeeeeee!
- This is really hard not to laugh at that.
I laughed. (buzzer)
- (Yogi) Laughter helps your asthma, bronchitis...
- I love the green screen and the effects
that he has in the background.
(Yogi wheezes, laughs silently)
- This is really, really difficult.
His silent laugh is extremely contagious.
- (Yogi) Now you can hug and laugh. (sniffs) Breathing.
(laughing more annoyingly)
- No. I'm not gonna laugh with you though.
(Yogi laughing annoyingly)
- I don't think he's that funny.
- (Yogi) Namaste laugh. (laughing piercingly)
(laughing continues) - (Katie) You smiled.
- Oh, I guess I'm out. (buzzer)
(Yogi laughing piercingly)
- (snickers) It's kinda really scary.
I [bleep] laughed. (buzzer)
(Yogi continues laughing)
- Those faces though. (whispering) Oh my god.
- (man, deep voice) Are you coming up to chill?
What's the plan, bro? Everything is awesome
when you're a pan-- - Fall.
NO! (buzzer)
- (man) Everything is awesome when you're a pan--
- (laughs uproariously)
(laughter stifling words)
(buzzer)
- (man) Everything is awesome when you're a pan--
(branch snaps in slow motion)
- I wouldn't laugh, 'cause I'd be afraid the panda got hurt.
- Oh, I love this kid. Love it.
- (spectators) Oh!
- Pain always gets me, 'cau-- kinda smile.
(contains laugh) Fudge!
Dang it! It was a double whammy!
(buzzer)
(people snickering) - Is that--
Is that his parent laughing? That's messed up.
- It's really hard not to laugh at this one.
(silence)
- (girl, on recording) Hey, sorry I missed your call.
Um... I'm just calling you back to, uh,
let you know that, uh...
I love you. - "Love you."
- (girl) And I miss you... - "Miss you..."
(girl cries like a motor) (imitates)
Love those two cars though.
- (girl) I know you're DONE. So... - Dignity.
- (girl) When you get this, can you call me back?
(crying like a motor)
I love you.
And I miss you. - That's such a fake cry.
(girl crying like a motor) - Not gonna lie.
Can I have those cars?
Like, can you guys just pass 'em over to me?
I'm about to start driving soon.
- (man) Hey, baby, slow down. Wait for me.
Oh wow, it's pretty rocky here, huh?
- She about to fall so hard; watch.
- (man) Hey, slow down on the rocks, baby. It's dangerous.
- It's very dangerous.
(thunder booms loudly) - (man) Jesus, come back here!
- Was that lightning?!
(thunder booms loudly) - (man) Jesus, come back here!
(woman screams) Oh my god, baby!
The bloody lightning bolt just missed you! - (cracking up)
(buzzer)
- (man) Baby, come back. The lightning bolt nearly hit ya.
Oh my god, baby, you all right?
(silence)

I'm not even sorry that I laughed.
