Johnny Walked Into His Parents' Bedroom...

He was surprised to see his parents were naked and his mom was bouncing on top of his dad. Mortified, his mom tells him to go to his room. After a few minutes of quick thinking she goes to Johnny to try to explain what he had witnessed.

"Johnny, your father's belly is so big that every once in awhile I have to bounce on top of him to push it back in," she exclaimed.

Johnny, just as puzzled as ever turned to her and said, "You're wasting your time, every day when you go to work Mrs. Jones from across the street comes over and blows it back up."
