My two favorite bumper stickers are still "I love animals. (They’re delicious)" and "Help stop inbreeding. Ban country music." Sorry to all the country and animal fans out there, but they’re funny. (or I’m just morbid) Also, we can’t forget one of my stickers. "Up, up, down, down, left, right, left, right, b, a, start." Sorry, you have to be a video gamer to get that one.
Up up down down, in addition to being the 30-extra-guys code for Contra, is the name of a band. I always thought that the bumper-sticker was for the band, not the nintendo game. But maybe not.
