A tour bus driver is driving with a bus full of senior citizens down a highway, when he is tapped on his shoulder by a little old lady. She offers him a handful of peanuts, which he gratefully munches up. About 15 minutes later, she taps him on his shoulder again and she hands him another handful of peanuts. She repeats this gesture about five more times. On the sixth time, he asks the little old lady why they don't eat the peanuts themselves, whereupon she replies that because of their old teeth, they are not able to chew them. "Why do you buy them then?" he asks puzzled. The elderly lady answers, "We just love to eat the chocolate around them!”
