Stewie can't control his messed up laugh, especially when watching shows like Hope and Faith.

From what I can tell this is from a Canadian show called "Just For Laughs".

A chain of laughing videos, each person laughing at the last person's laugh. Includes the 'hnyuk hnyuk' guy from the Comedy Barn.

I'm so glad that comedy shows have laugh tracks, otherwise I wouldn't know when to laugh. Now someone took some drama shows like 'The Wire' and added laugh tracks to them too. Awesome! Otherwise TV might be too gritty and depressing.

John Pinettes First appearance on Just for laughs back in the 80's, sorry about the quality, but it's the only full-clip I could find.

This is a series of clips where some people have lost it to uncontrollable fits of laughter/hyperventillation! The very first of the clips is the same as this one... http://www.videosift.com/video/My-Laughing-Breakdown-on-Call-for-Help Enjoy!

I miss Laugh-In being on Nick at Nite every night.

Can you dig the truth: PS3 makes babies cry, and the Wii makes them laugh.

Little guy is learning to spit after brushing his teeth. The "PA-TU-EY" sound is pushing his laugh button. SUPER cute!

Baby can't decide to cry or laugh . . .
