Stolen Billfold

John was driving home late one night when he picked up a hitchhiker. As they rode along, he began to be suspicious of his passenger. John checked to see if his wallet was safe in the pocket of his coat that was on the seat between them, but it wasn't there! So he slammed on the brakes, ordered the hitchhiker out, and said, "Hand over the wallet immediately!"

The frightened hitchhiker handed over a billfold, and John drove off. When he arrived home, he started to tell his wife about the experience, but she interrupted him, saying, "Before I forget, John, do you know that you left your wallet at home this morning?"
