That's Not Going to Help

One day a boy approached his mother with a question. "Mom, how come every night I hear you and daddy fighting and yelling, but when I look in your room you're on top of each other?"

His mother ,very surprised, replies; "Honey you know how fat daddy is, I'm jumping on top of him to help him lose weight".

The boy knows that's not working and tells his mother why...

"Mom that's not going to help, because the lady next door comes by after you leave for work, and blows him back up again!"
