My all time favorite cartoon has got to be Mickey Mouse. I have a thing for Disney cartoons/movies TV shows. They have something magical about them. Of course, I'm only talking about the traditionally animated stuff from them, and not the recent computer generated animation crap they have been dishing out, year after year.
Lilo and Stitch. I could always identify a lot of parts of my childhood with Lilo (Luckily not the "no parents" situation, but just being a weird kid who loved horror, Elvis and was bullied for being different)
Peter Pan. Not for Tinkerbell but because I like the actual idea of an island existing with pirates and mermaids, swashbuckling and whatnot... Besides, I'd love to fly around without a care in the world. :3
