An elderly couple goes to Burger King and shares their fries and burger. A trucker sitting next to them offers to pay for the old lady. "It's all right," says the old man. "We always share everything." On seeing that the old lady has not eaten anything, the trucker once again makes an offer. The old man once again assures the trucker to stay calm and resumes eating. Finally, the trucker asks the lady about not eating anything. The old lady replies, " I am waiting for the teeth."
