Little Johnny was at the breakfast table with his parents one day and his mother asked him why he looked so tired as he had an apparent look of sleep deprivation. He exclaimed "I haven't gotten any sleep for the past week because you and daddy are always making so much noise! Then when I walk in the room, you're there bouncing up and down on his belly! What are you guys DOING and why?!"
His mother embarrassed replied, " You see honey, daddy's really fat, so mommy has to bounce up and down on his belly each night to squeeze all the air out of him."

Johnny says, "Well that won't work mommy."

mom " Why not johnny?"

Johnny " Well because every time you leave for work in the morning the neighbor lady just comes over and blows him back up."
