Little Johnny's dad is sitting on the side of the bed rolling on a
condom about to give his wife some. 
Little Johnny sticks his head in the door, sees his dad and says,
"Whatcha doin' Daddy?" 
Johnny's dad stoops over to cover up his dick and starts looking at the
floor. "Oh, I'm just looking for this big rat I saw." he says. 
Little Johnny asks, "Whatcha gonna do, fuck it?"
