Good pro wrestling, writing, psychology, sociology, MMA, Batman.
I would be completely content if I could have a conversation with Keiji Mutoh, even if that conversation was entirely about the Shining Wizard. To those not in the know, a Shining Wizard is a step up knee strike to the face or side of head. I enjoy knee strikes.
Punk rock kid at heart, but I can get into most things that manage not to suck. I feel like I've been listening to movie score music more than anything lately. And Beethoven. It varies.
Taxi Driver, The Usual Suspects, Blade Runner, The Warriors, American Psycho, Goodfellas, Fight Club, Chris Nolan films in general, good comic book flicks (Sin City, 300, Batman Begins) and so on.
House, Conan O'Brien, Supernatural, my growing TV-on-DVD collection (good Simpsons, Futurama, American Dad, Family Guy, Arrested Development, classic Twilight Zone and all four volumes of Batman: The Animated Series.)
Dostoyevsky, crime noir, comic books, Grant Morrison, Alan Moore, Frank Miller, many more. Books on psychology. Pretty much anything that's a book.
