One night, a little kid wakes up and goes to the bathroom! As he was going to the bathroom, he sees his mom jumping on top of his dad's belly. Next day, the little kids asks his mom:
-"Mom, why were you jumping on top of dad's belly?"
-"Where? What? You saw us?"
-"Yes, while I was going to the bathroom."
-"Ummm, because your dad's belly is fat, I jump on him so I can deflate his belly."
-"Mom, it's not worth it! In the morning, when you are not around, a Russian girl comes to our house does the jumping on him!
