A husband and wife and their two sons are watching TV. The wife looks
at her husband and winks. He gets the message and says, "Excuse us for
a few minutes, boys, we're going up to our room for a little while."
They go upstairs to their room and leave the boys with the TV. Pretty
soon one of the boys becomes curious, so he goes upstairs and sees the
door to his parents' bedroom is ajar. He peeks in for a few minutes,
then trots downstairs, gets his little brother and brings him upstairs
to peek into the bedroom too.
"Before you look in there," he says,
"keep in mind this is the same woman who paddles your butt for sucking
your thumb!"
