How does a dissatisfied Obama voter get rid of his or her Obama bumper sticker?

With "the old B.S. scraper," according to conservative vendor American Tees. (With B.S. clearly standing for bumper sticker).

This week the company introduced a B.S. removal kit on its Web site and created a YouTube ad to go right along with it. The advertisement asks, "Has this ever happened to you? You vote for a charismatic young politician only to be disappointed by his undelivered promises of hope and change?" The ad touts that the kit "even works on a Prius."
