A tour bus driver is driving with a bus load of seniors 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 up.
After about 15 minutes, she taps him on his shoulder again and she hands him another handful of peanuts .
She repeats this gesture about five more times .
When she is about to hand him another batch again he asks the little old lady, 'Why don't you eat the peanuts yourself?' .
'We can't chew them because we've no teeth', she replied .
The puzzled driver asks, 'Why do you buy them then?'
The old lady replied, 'We just love the chocolate around them.'
It pays to be careful around old people......
