This little boy wakes up 3 nights in a row when he hears
thumping
coming from his parent's room. He goes to his mom and
says, "Mommy,
every night I hear you and daddy making noise and when I
look in
you're bouncing up and down on him."
His mom is taken by surprise and says, "Oh... well I'm
bouncing on his
stomach because he's fat and that makes him thin
again."
The boy says, "That won't work."
His mom says, "Why?"
The boy replies, "Because the lady next door comes by
after you leave
each day and blows him back up!"
