I was born this way baby
One day a little boy walked into the kitchen where his mother was working at the counter.
"Mommy, I heard a thumping sound coming from your and Daddy's bedroom last night. When I went in, you were on top of Daddy and bouncing up and down. Why do you do that?
The mom, stunned says quickly, "Uh, your Dad is overweight. I bounce on him to get the air out."
The boy scoffed, "Your wasting your time. When you go to work, the lady from next door comes over and blows him right back up again."
