A tour bus driver is driving with a bus load of OAPs when he is tapped on his shoulder by a little old lady.

She offers him a handful of peanuts, which he gratefully munches up.

After about 15 minutes, she taps him on his shoulder again and she hands him another handful of peanuts.

When she is about to hand him another batch again he asks her: "Why don`t you eat the peanuts yourself?"

"We can't chew them because we've no teeth", she replied.

"We just love the chocolate around them."
