My friend Pau's son Kai had a beach day with his class. He would climb on Paul and Paul would toss him into the water.
That led to half a dozen other kids all wanting to climb on Paul as well. In order to peel them off, Paul would tickle whoever was on his back then toss that one into the water. All the kids took turns climbing on and getting tossed, except a blonde-haired girl.
Later Paul found out why. Paul asked her if she liked to be tickled and she said, "No, when my older sister tickles me, I pee a little."
Hope your day is so much fun you wet your pants!
