When I was in high school, I was vaguely acquainted with a guy just a year or two older than I was. Tough kid. He was a drop-out, but he hung around school trying to score girls.

He claimed to be equipped with "twin screws."

"'Twin screws?'" said I. "What do you mean?"

He said he had two propellers tattooed on his rump, one on each buttock.

I took his word for it.
