Just at the top of my head...
The Muppet Show (yeah... for obvious reasons...).
Sesame Street (yeah, again, no surprise there.
And I also love
Play With Me Sesame, because it has older sketches).
Fraggle Rock (I've loved it for as long as I've loved SSt, so it only makes sense).
Seinfeld (One of the few American comedies that make me laugh-out-loud).
The Simpsons (I love it. x33 Watching it is a daily ritual).
Family Guy (though to be honest, it's really sucky now. It was brilltastic when it started out, but now it's just not funny, so I've sort of laid off it a bit).
Neighbours (... ... ... guilty pleasure!).
Harvey Birdman: Attorney At Law (I absolutely love it, but I didn't love how it ended. xP).
Metalocalypse (It's fantastic! But possibly rather terrifying for people who don't quite understand the metal culture and think anyone with long hair is like Dethklok.
).
Happy days (I have the books. xP).
Jem (Possibly my favourite cartoon of the 80's).
Animaniacs (been a fan since I was little!).
Goof Troop (Brings back a lot of nice memories).
The Storyteller (I miss this show! D: )
Top Gear (It's gone off a bit, but I still love it dearly).
House (The cinematography side of it is exceptional. I wish it was on more...).
The Big Bang Theory (sometimes. But yeah, pretty much a guilty pleasure).
Daria (I used to watch this when it first came out. xDD I appreciate more now, though).
I Dream of Jeannie (I love it. c: ).
Benny Hill (so bad it's good... anglophilia runs in the family.
)
Monty Python's Flying Circus (I used to listen to my Dad's Python records when I was really young, and then I saw the films when I was about 10, and I finally got into the show.)
