I once saw a cat get its hind part smashed by a car. It was trying to get to the side of the road using its front paws. The look of terror on that cat is ingrained in my head ... and all that was going on while I glanced out my window going 60 mph.
I'm suprised "lipstick on a pig" didn't show up. I heard that one for the first time in 2003 when a co-worker was describing a nearby city. Then when Barack "the Rock" Obama used it, it seemed the phrase became much more popular.
