From davezilla:
Growing up I had a neighbor, a wealthy man with two Rolls Royce sedans.
He drove the powder blue one everywhere. It had, [sigh] a bumper sticker. I know. On a Rolls. There�s a special place in Hell for people who put bumper stickers on $100,000 cars. Especially for his bumper sticker. It read: My other car is a Rolls Royce. And it was. I hated him.
Worse still. His license plate, a vanity plate of course, read HUMBLE. I know. I balled up my fists when first I read it too.
