Jimmy had been hearing loud bumping noises coming from his parents room for the last 3 or 4 nights. The next night , the noises started again, so he goes to investigate.
Quietly opening his parents bedroom door, he see's his mother bouncing up and down on his father. Quietly, he slips back to bed. The next morning, Jimmy asks his mom why she was bouncing up and down on dads stomach. Mom thinks for a minute , then tells Jimmy it's part of a new diet plan to help dad lose weight.
Jimmy then replies" I don't think it will work mom". Mom asks Jimmy why not! "Because every morning when you leave for work, Mrs. Jones from next door comes over and blows daddy back up!"
