A little boy walks into his parents' room and sees his
Mom bouncing up and down on his Dad. The
parents stop; the mother dismounts and
pulls the sheets around her.
"What were you and Dad doing?" the
boy asks his Mom.
"Well, your Dad has a big tummy and sometimes I have
to get on top of it to help flatten it," she explains..
"Aww Mom, you're just wasting your time," says the boy.
"When you go shopping, the lady next door gets on
her knees and blows it right back up."
