A little boy often heard thumping noises from his parent's bedroom. One night, he crept from his bedroom and peeked into his parents bedroom and saw his mom on top of his dad.
The next day he told his mom what he saw and wanted to know what she was doing on top of his dad. His mother was shocked and embarrassed at the same time. She tried to make it look very casual.
She said, "Oh, your daddy is too fat, so I was trying to slim him down."
The boy then immediately replied, "It's no use because the lady next door comes around when you're not in to blow him up again."
