Two not-so-bright guys are discussing one's upcoming wedding. "I'm not sure if
my future bride is a virgin or not."
His buddy replies, "Oh, there's an easy test for that. All you need is some
red paint, some blue paint and a shovel. You paint one ball red and one ball
blue. On your honeymoon, if she laughs and says, "'Those are the funniest
balls I've ever seen!' you hit her with the shovel!"
