Music:
50's & 60's rock, psychobilly, punk, oi!, ska, reggae, hardcore, rock and roll in it's many forms really. has to be good and raw, nothing that sounds too damn manufactured although there are always exceptions, sometimes the right ingredients are just there. i'll one day actully list some bands but i'm slack.
Movies:
horror, sci-fi, fantasy (medieval type shit), anime, comedy
Television:
simpsons, futurama, red dwarf, the young ones, buffy, angel, firefly, the goodies, the d-generation, king of the hill, little britain, the league of gentlemen, hell of a lot of anime...
Books:
the discworld series by terry pratchett, anything else by pratchett. anything by douglas adams. jrr-tolkien. there are far too many to list here yet I haven't read a book this year which is just a tad shocking for me to realise as i type this.
