Sex Education

[paddyk]

Teacher is doing a first sex education class.
She draws a picture of a peni$ on the board and asks the class "Does anyone know what this is ?"
Little Johnny puts his hand up and says "Please Miss - I know what it is and my Dad has two of them !"
The teacher says "Johnny, that's impossible - he can't have two"
Johnny says " Yes he has Miss - a small one for peeing with, and a big one for brushing the babysitter's teeth !!"
