Ummm... coining nonsense portmanteaus? Coming up with ridiculous ideas? Seeing the humor in every situation?
I haven't been reading as much lately as I would like to, but I have a whole list of postmodernist fiction I'd like to read. All-time favorites are the usual suspects: Gatsby, Crime and Punishment, the Good Earth, Catcher in the Rye. Stuff I read as a teenager that had a great effect on me, I suppose.
I'm also really into superhero comics, and frequently obsess over whatever Grant Morrison or Neil Gaiman write.
TV... I just watched through every Joss Whedon series - Buffy, Angel, Firefly, Dollhouse - and the early seasons of the Simpsons are a perennial favorite. I've watched Freaks and Geeks through about 6 times.
As for movies, I could watch The Big Lebowski or the Dark Knight any time. I know, dork.
