A bus driver with a bus full of seniors is driving 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. After approx. 15 minutes, she taps him on his shoulder again and she hands him another handful of peanuts. She repeats this gesture eight more times. At the ninth time he asks the little old lady why they don't eat the peanuts themselves. She replies, "we can't because of our teeth, we can't chew them." "Why do you buy them then?" he asks puzzled. The old lady answers, "We just love the chocolate around them."
