Road Trip. Picked it up from a car boot for 50p and haven't seen it since I was 13 or so.
Don't know what I was expecting. Well I do, and it was that. Awful, but I did nearly vomit laughing when the old man had the boner and then when his dog said 'get that bitch to make some blueberry pancakes'. Easily pleased, and incredibly fucked by the time I watched it.
