You... unless you're one of those scantily clad women with 9,024 friends and are asking me to be your friend so you can break 10,000.
Rock whether it's classic (Stones and Beatles), hard (Sabbath and Metallica), 80's (Springstein and Aerosmith), 90's (Pearl Jam and Rage) or whatever the hell we're calling this decade (Killers and Audioslave)... Also on a bit of a blues and Mototown kick lately. But basically whatever I'm feeling at that moment.
Too many to list but I love everything from Amadeus to Cadddyshack to Network to Annie Hall.
Arrested Development (I refuse to acknowledge it was cancelled), The Daily Show, Lost, Entourage, Flight of the Concordes, The Office, South Park, and as many geeky Nova and History Channel shows as I can fit on my Tivo
Anything historical, introspective, or hilarious. Bonus points if it's all three. Just read a Brief History of Nearly Everything by Bill Byson and it's one of best books I've ever read.
