What a crock. I don't believe that for a second. Either the friend is lying or the Limey is lying. Now that I think about it, the Limey is probably lying about having a friend let alone a friend whose car had a moronic bumper sticker stolen.
What John le Crocke forget to tell you was that his friend in California was driving an SUV, and that the Pinko Peacenik bumper sticker wasn't stolen, but replaced, by another bumper sticker accusing him of being a terrorist.
