Movies: Comedies of all sorts, maybe some drama, perhaps some fantasy
Shows: Louie, The Office (UK and US versions), Extras, The Ricky Gervais Show, Monty Python's Flying Circus, The Goodies, Black Books, Peep Show, Coupling, Blackadder, The Mighty Boosh, Community, The IT Crowd, A Bit of Fry and Laurie, Arrested Development, Green Wing, Workaholics, It's Always Sunny in Philadelphia, QI, The Sarah Silverman Program, Scrubs, Cheers, Seinfeld, Family Ties, Friends, The Big Bang Theory, Fawlty Towers, Skins (UK version), Archer, American Dad, Family Guy (sometimes), Futurama, The Simpsons, Monster, Welcome to the NHK, Lucky Star, Azumanga Daioh, loads of other anime, various others. I watch far too much television.
Music: Most genres, but I have extra love for blues, folk, jazz, black gospel (despite my atheism), soul, funk, early rock and metal, punk, post punk, dream pop, shoegaze, noise pop, ska, rocksteady, reggae, dub reggae, oldschool hip hop, trip hop, jungle, 2-step garage, early dubstep (it doesn't all sound like Skrillex), IDM, anything experimental and interesting. So that narrows it down.
Food: Whatever is literally the worst possible thing for me to be eating. And watermelon.
