Music:
Anything by Bad Religion, Social D, Flogging Molly, Blue October. For the most part, country makes my skin crawl, but I like the old school stuff--Merle, Hank, etc.
Movies:
Grosse Pointe Blank, So I Married an Axe Murderer, Army of Darkness, anything Monty Python ever did, Braveheart (hey, I'm Scottish).
Television:
Not so much, but I guess if I had to pick it would be the History Channel, Discovery Channel, and Speed Channel. Sometimes Comedy Central, especially Adult Swim.
