In Las Vegas, a drunken man stumbled into an Automat. He reached into his pocket, pulled out some coins, and put them into one of the machines. He received a ham sandwich. He put more coins in, and got another sandwich. He kept doing this until he had a small pile of twenty sandwiches.
One of the other people in the automat and asked him, “Don’t you think you have enough sandwiches now?”
The drunken man replied, “Why should I quit while I’m ahead?”
