Tour bus driver

A tour bus driver drives with a bus full of seniors down a highway, when he is tapped on his shoulder by a little old lady. She offers him a handfull of peanuts, whcih he gratefully munches up.

After approx. 15 minutes, she taps him on his shoulder again and she hands him another handfull of peanuts. She repeats this gesture about eight times.

At the ninth time, he asks the little old lady why they do not eat the peanuts themselves, whereupon she replies that is is not possible because of their old teeth, they are not able to chew them.

"Why do you buy them then?" he asks, puzzled. Whereupon the old lady answers, "We just love the chocolate around them!"
