5. Reptar (Rugrats)
Reptar not only excels because it's a show about a freakin' dinosaur, but because it so lovingly and accurately portrays that nostalgic feeling of loving, really loving, a bunch of stupid stuff when you were a kid. But mostly the dinosaur part.
4. Everybody Loves Hypnotoad (Futurama)
EVERYBODY LOVES HYPNOTOAD
3. The Terrance and Phillip Show (South Park)
Perhaps best known for their ill-fated marriage to the Queef Sisters, (OK, not really, but damn it if I'm not going to use that word when given the opportunity) Terrance and Phillip acts as a reaction to the reaction South Park received by viewers. Hats off to Trey Parker and Matt Stone, who found a beautiful way to marry clever, defensive social commentary with as many fart noises as they could ever want or need.
2. Troy and Abed in the Morning (Community)
We've only ever seen brief glimpses of Try and Abed in the Morning, but that hasn't stopped it from becoming one of the most talked about morning TV shows of all time. Probably because the only people who were talking about morning TV before this were only talking to their eight (at least) cats. The set up is simple: Troy and Abed set up an interview with a well-known Greendale student, then talk them into a furious rage. It airs 6 a.m. (EST). On no channels.
1. Itchy and Scratchy (The Simpsons)
I wasn't allowed to watch the Simpsons until I was 10 because my parents had seen Itchy and Scratchy one time. Not that it stopped me from watching the show. Itchy and Scratchy is actually a show-within-a-show-within-a-show, appearing as a segment on The Krusty The Klown show. Not only is it the most popular cartoon in the history of television, but it's really seriously violent in all manner of disgustingly creative ways. Itchy and Scratchy doesn't come with any real edifying message, or any real intent of artistic parody (besides a vague association with Tom and Jerry), but that's what's so magical about it. It's a show all by itself, and could be even without the frame of being based in The Simpsons.
