The Simpsons - fan since day one, and my all-time favorite show by the end of the first season...
Family Guy - another favorite, endlessly quotable and hilarious...
South Park - see above...
Saturday Night Live (1975-1980) - the first five years of this groundbreaking comedy series, with Dan Aykroyd, John Belushi, Chevy Chase, Jane Curtin, Garrett Morris, Bill Murray, Laraine Newman and Gilda Radner. I was first exposed to it via the 30-minute syndicated "Best of SNL" series; I never thought I would see the full, complete, uncut seasons (including the musical guests) on DVD!
So far they're up to the fourth season...
Monty Python's Flying Circus - can't get enough of this show; even in the Cleese-less final season, there's a lot to like...
Fawlty Towers - THE perfect sitcom IMO, starring John Cleese...
SpongeBob Squarepants - SpongeBob is fantastic, but to me, Squidward is the true star...
Batman - the classic 1966-68 live-action series, starring the one and only Adam West...
Married...with Children - Whoooooooaaaaaaa Bundy!
Mr. Bean - love Rowan Atkinson...
The Muppet Show - a variety show featuring...muffins...moppets...magpies...something like that...
