This is difficult.. I don't think I can pick just one! (And of course, this does not include anime =P)
I love Rocko's Modern Life because it's so random and weird, and hilarious. How can you not love Filbert? "Oh, fishsticks!"
And don't forget The Simpsons, Family Guy, Futurama, South Park, Ed Edd n Eddy, and Home Movies.
Home Movies is one not a lot of people have seen/heard of (from my experience), but it is so incredibly funny..
Ah, that defeated the purpose of your favorite CARTOON (singular). Oh well ^_^

Snoopy - Do I need a reason. He is just the sweetest, funniest little dog there is. And I collect the books and even have a snoppy telephone

Favorite anime? Oh gosh, there's too many! Trigun, Cowboy Bebop, Lodoss, Evangelion, Kare Kano, Serial Experiments Lain, Fushigi Yuugi, Excel Saga, and I want to see more Fruits Basket.. and that's not even close to all the anime I've seen, and it also doesn't include manga.. ah, I could go on for hours...

Yeah I think so too!

Yeah, that is a little strange. It's okay, 'cause I'm pretty weird too. I like Futurama too, and King of the Hill, but I like the Simpsons better.

the simpsons are funny... I think I've seen every episode like ten times when I was a kid I used to adore scooby doo and the smurfs. cartoon in terms of comics, I LOVE garfield, he's the best!

Inyuasha, Garfield, Furtrama, Simpsons, Scooby Doo., Wolf Rain.

Peter Pan, but not And the Pirates, another version that no ones seems to nkow
