Didn't I say this already? Music and sports.
Chris Cornell and Tom Morello (Audioslave), Maynard Keenan (Tool), Dave Grohl (Foo Fighters)
Tons. Anything from blues (Clapton, BB King, Allman Brothers) to rock (Audioslave, Soundgarden, Queens of the Stone Age) to metal (Megadeth, Black Label Society) to progressive (Dream Theater, Tool, The Mars Volta) to funk (James Brown, Moses Mayes, Kool & The Gang). I could talk your ear off about music.
Pulp Fiction, Sin City, Boondock Saints, FUBAR are my favourites. I'm also a fan of the zombie thrillers (Day of the Dead, Night of the Living Dead, etc). My girlfriend is a movie fanatic, so she can hook me up. ;)
Family Guy, Chappelle's Show, The Office (British Version). Whose Line is it Anyway is a genius show as well.
Anything by Stephen King or Chuck Palahniuk. Lord of the Rings, the Narnia Chronicles...my university textbooks (yeah right).
Any member of my favourite bands. My parents. Whoever invented pizza.
