I went to a party the other day where a dude had such a sticker on his car outfront. When I went in, I said, "I have an anouncement, it appears there has been a pratical joker in the parking lot. Someone has placed a Bush/Cheney bumpersticker on a white SUV in the parking lot."
I got a lot of laughs, but the dude whose car it was, was drunk, later he came over to me and said he was proud of his bumper sticker.
