That's a good one, how's this?
A blond guy comes home early one day from work, and hear's moaning noises coming from the bedroom. So, he runs upstairs and finds his wife naked, sweating and panting heavily, she says"I'm having a heart attack", so...he runs downstairs and picks up the phone to dial 911, as soon as he does his lil boy comes downstairs and says, "Daddy, Uncle bill is in your bedroom closet naked"> Furious, he runs back upstairs, rips open the closet door and sure enough, cowering in the closet, naked...is Uncle Bill. He roars, "How dare you be in here while my wife is having a heart Attack!"
