Playing/listening to music, politics, getting very drunk very often, general dossing about.
Winston Churchill, Maggie T, the cast of the OC and David Bowie. Oh and the guy who wrote the crazy frog so i can punch him in the face.
All the classics; Bob Dylan, Beatles, Rolling Stones, Bowie, Britpop; Blur, Oasis, Supergrass. Modern Indie; Shins, Modest Mouse, oh and a bizarre and desperately uncool obsession with Johnny Cash!
Anything with zombies in it, anything by John Carpenter, particularly Assault on Precinct 13. The Bill & Ted Films. Dr Strangelove is good too.
Garth Marenghi's Darkplace, The Day Today, Alan Partridge, Yes Minister, The West Wing, 24, Nip/Tuck and of course the OC (even if i do really know its shit)
On The Beach (the one about the end of the world not the one with Leanardo Di Caprio), Freakenomics is a great book, The Skeptical Environmentalist should be read by everyone.
Was arguably David Bowie's best song, although I reckon his drum and bass album 'Earthling' has a lot going for it.
