An actuary and an underwriter are watching the eleven o'clock news. A story comes on involving a man on a window ledge threatening to jump. The underwriter says, "I'll bet you fifty bucks he doesn't jump." The actuary says, "I'll take the bet."

A few minutes later they see that the guy does indeed jump. As the underwriter reaches for his wallet, the actuary says, "Never mind. It's not fair. I saw it on the six o'clock news." The underwriter responds, "So did I, but I just didn't think it would happen twice."
