This and the Golden Girls clip are two of my favorites, too. Soooo funny.
God, I love that one.
Moving from IMHO to MPSIMS.
I’ve always wondered who it is who laughs at the cartoons in the New Yorker. Now I know!
(Actually, I think it was on here that somebody gave me the Secret Key for enjoying New Yorker cartoons. They’re all actually very funny if you change the caption on every single one of them to “Christ, what an asshole!” It’s sort of like that Garfield Without Garfield thing, I guess.)
Holy shit! For years and years and years I’ve had “My hemets and my shouldermapads” as part of my vocabulary, but I had no idea where that originally came from. Thank you so much for that link.
My contribution… I know that we should provide a short explanation for our videos, but you really have to go into this one tabula rasa.
John Stewart’s long parody of Glenn Beck is tearfully brilliant. He was on perfect comedy form in this one.
I think Victor Borge was one of the funniest people in history. He was only a piano player, yet some of his stuff was funnier than most stand up comedians have.
A few of his funniest moments (in my opinion):
I think you might actually be referring to a skit from the Jack Benny show between Jack and Mel Blanc:
Hells yeah on the Victor Borge.
I’m not a huge fan of Steve Martin making funny faces, but this clip from Dirty Rotten Scoundrels had me in tears:
The final “around and up the tetherball pole for the spike” had me on the floor. 
“The Price is WRONG, BITCH!” scene with Adam Sandler and Bob Barker, in Happy Gilmore.
Some people have no freakin’ idea about cats.
There’s a Let’s Player goes by the name of Cry. He’s generally pretty funny. Especially his reactions to horror games.
Someone compiled some of his funniest scary moments. I giggle throughout, then absolutely lose it with the Which clip near the end.
I remembered this in the “what’s this six foot bird” thread and I had forgotten just how hard it made me laugh - this really did appear in a REAL NEWSPAPER (and showed up the next day on the front page of my local paper as well): Wild goose chase nets emu near downtown Rock Hill.
“The chasers, who by now numbered at least 50 and included neighbors, city workers, women in hair curlers and one guy who had a cold beer but did not share, cheered.”
That reminds me - one of the funniest things I’ve ever seen was also on the Daily Show - John Lithgow solemnly reading a recent speech, verbatim, of Newt Gingrich.
ETA: My mistake, the Colbert Report. That entire episode is one of his all time best.
WKRP in Cicinnati.
“God as my witness, I thought turkeys could fly”
