Young Johny comes home from school a bit confused, and asks his dad.
"What's the differance between a Vigina and a c***?"
"Well son l'll show you" says his father and takes him up stairs to the bedroom where his mother's sleeping. Lifting the blankets he says "look there son between your mothers legs, that hairy thing is a Vigina".
"Can l touch it father" says Johny.
"No son you'll wake the c*** up"
