FreakazoidI learned many things from it. Mostly, how to be really annoying. They teach you how to say, "Who cut the cheese?" in about five different languages. One of my favorite bits is in the first episode:
DEXTER: My computer is my life.
MOM: That's so very, very sad.
There's also a musical episode in the 2nd season that is a must watch.
"Hey, Lobey. How ya doing, Lobey? I'm so pleased to see you I just have to scream." *cuts away to a scene from an old horror flick that shows a woman screaming* "We're just pleased to see your big, fat head."
And also, I learned some men never get married because they like meat too much.
