Little Johnny came home very early and very unexpectedly from school one afternoon and found his mom and dad making love on top of the bed. "What are you doing to mom, dad?" asks Johnny. "Don't worry, son," says Dad, "I'm just filling your mom up with petrol." "Gee, dad, she doesn't do many miles to the gallon does she?" says Johnny. "What do you mean, Johnny?" asks dad. "Well", says Johnny, "I saw the Rawleigh's man filling her up at lunch time."
