I can’t think of a single routine of George Carlin’s that deserves to be listed, but I do think his entire two segments/routines on Airport language and security have made me laugh almost more than anything else.
Brian Regan, “Stupid in School”. I could basically just agree with the entire act that comes from; to this day I can’t think about it without laughing.
When my niece was just learning to walk, I was sitting with my sister and we were watching her walk a few steps and then fall back on her butt, then stand up and do it again. After one plop, my sister turned to me and deadpanned: “She’s no fun, she fell right over”. We both nearly fell off the couch laughing.
I agree. I first “heard” it when I visited the Baseball Hall of Fame in Cooperstown as a kid. It just awed me. The brilliance of the wordplay turned out to be matched by the awesome timing when I finally found an old radio tape and film performances. It’s perfection. Maybe Monty Python’s Cheese Shop is the only rival I’ve seen. Too bad Firesign never filmed Nick Danger.
I’ll toss out a wild card that nobody else will be able to doubt because nobody else probably ever heard it. I saw A. Whitney Brown of SNL fame in a small room - think of the cabin scene in A Night At the Opera. He didn’t tell jokes, but delivered stories in his famed offhand manner. They were hilarious. I’ve been to shows that were funnier as a whole - Dennis Miller’s White Album tour and Lewis Black’s Black Album tour were killers - but for the amount of laughter per cubic feet in a venue, Brown leads the pack.
