An old lady offers the bus-driver some peanuts… So, the driver happily munches them.
Every 5 minutes she gives him a handful more peanuts.
Driver: Why don’t you eat them yourself?
Old lady: I can’t chew. Look, I have no teeth. She smiles to prove it.
Driver: Then why do you buy them?
Old lady: Oh, I just love the chocolates around them.
