Looking for Mice

A man and his wife have just finished having sex and
he is in the bathroom removing a condom. Unexpectedly,
his little boy walks in and says, "Daddy, what are you
doing?".

The father, not wanting to tell his young son what he
is really doing says, "Oh, I was just looking for mice".

The little boy looks puzzled, then says "What are you
doing? Screwin' em?"
