A woman teacher is teaching her class of seven year old pupils about the birds and the bees. She displays a diagram of a mans body. Pointing to the penis, she says, "every man has one of these." A boy at the back thrusts his arm up and says, "that's wrong Miss, my Dad has two of those." The teacher replied, "I think you are wrong there all men have just one penis." The boy replied, "no my dad has two, a small one he uses to piss, and a big stiff one he cleans the Au Pairs teeth with."
