A little boy wakes up three ***hts in a row when he hears a thumping sound coming from his parents' bedroom. Finally, one morning he goes to his mom and says, "Mommy, every ***ht 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!"
