A coach driver was taking 50 pensioners on a trip to Spain.
After a while an old lady tapped him on the shoulder and offered him a handful of peanuts.
He ate them, gratefully.
Over the course of the journey the kindly lady gave him several more handfuls of peanuts, until finally he put his hand up, saying: "Please, you should eat some yourselves."
"We can't," she said . "They get under our dentures."
"Then why buy them?"
"Because we like the chocolate they're covered in."
