Old episodes of The Cosby Show have had me in stiches.
Many of the other picks in this thread are also very good.
Whose Line Is It Anyway?
The Simpsons
Family Guy
Sailor Moon
Spongebob Squarepants
MXC (Most Extreme Challenge)
Agh how could I forget ** The Cosby Show**? Sorry about that.
Scrubs is the only show that I can recall that had me laughing so loud that I missed the next joke. (mostly because the jokes are so rapid-fire)
I laugh at Scrubs, Frasier, Whose Line, and America’s Funniest Home Videos (but only the ones with the newest host, Tom Vergeron or whatever his name is. I don’t like any of the other hosts.)
In addition to those mentioned already:
**Fawlty Towers **
The Man Show (mostly bad but some great laughs, especially with Man Show Boy)
Just Shoot Me
The Daily Show
MST3K
Cheers
Arrested Development
Futurama
Family Guy
Aqua Teen Hunger Force–“I will not walk so that a child may live!”
The Simpsons
The Venture Brothers
Strangers with Candy practically makes me pee myself, even watching them over and over. I just laughed out loud thinking about Onyx Blackman’s manboobies just now. In this month’s Bust Maya Rudolph interviews Amy Sedaris and I was reading it in the bathtub and there’s a photo of Jerri doing some chemistry with goggles on and man was I laughing. Laughin in the tub. You have to see this issue, it has a photo spread of Amy with gigantic fake nipples in a variety of nipple-enchancing outfits.
The first time I ever saw Kids in the Hall a vein in my forehead got overtaxed from me laughing too hard and I got a headache.
Also,
Chappelle’s Show
Daily Show
Arrested Development
Mr. Show
Simpsons
I always wind up laughing out loud during Weekend Update and often during SNL when they have Appalachian Emergency or certain other things. If something is supposed to be “comedy” but it doesn’t make me laugh I don’t want anything to do with it. I think it might be bad for the soul. Like, if I have to watch Ray Romano do anything I think it is like negative laughter or something to look at people acting like idiots without laughing. It’s the inverse of laughing. There’s something wrong with that experience.
The Office (BBC), Arrested Development, Strangers With Candy and The Simpsons are all great for a laugh. But never do I laugh harder at a TV program than whenever Conan O’Brien is really on a roll.
