My friends tell me I can be very witty, I generally find that's only the case when I don't try too hard (at least that when they laugh the most). I have a somewhat dry/sarcastic sense of humour which sometimes teeters on the edge of the surreal.
I like to think of myself as a realist (but I know some people would consider me a pessimist), but even when things go wrong I can often find a sort of ironic, grim amusement from it.
I'm a bit of an introvert, I find large social group to be exhausting, and I tend blend into the background, but I do like to spend time with good friends and have long rambling conversations that when you reach a natural pause, you sometimes wonder how the heck you ended up talking that. I know tons of useless information, unfortunately because it's useless, it's not particularly useful in pub quizzes (darn it all)
I also like the work of Brandon Sanderson, Douglas Adams and Terry Prattchet.
Movies: I like movies which make you think, I'm a big sucker for movies which start in media res, but a high octane action movies can also be good providing it doesn't try to take themselves seriously and/or rely on the "star power" of the main actor(s).
Shows: I'll give anything by Joss Whedon a try (loved Firefly), and if it's Sci-Fi or Fantasy, I'll almost always give it a try.
Music: Hard to say, I don't generally listen to much but if I hear it I like a bit rock/metal music (not thrash metal though), or classical. I really can't be doing with Rap music though...
Food: Not really into spicy foods, I'm a complete spice wimp, if it's hotter than black pepper, I probably won't like it.
I could live without pretty much everything if I had to, but I would miss my computer.
