Little Johnny walked into his dad's bedroom...

Little Johnny walked into his dad's bedroom one day and caught him sitting on the side of his bed sliding on a condom.

Little Johnny's father (in an attempt to hide his wood) bent over as if to look under the bed.

Little Johnny asked, "What are you doing, Dad?".

His father replied, "I thought I saw a rat go underneath the bed!".

Little Johnny replied, "Whatcha gonna do - screw him?".
