One night, Sammi was taking her nightly bath while I sat in the next room reading.
Sammi (screaming suddenly): "Daddy!!! Come quick!"
My heart skipped a beat as I immediately jumped up and ran into the bathroom where I was greeted by my daughter standing in the tub, bending over - showing me her bum.
Me: "Wha...what happened?!?"
Sammi: "I fell over and broke my butt. See? It's got a crack in it!" At which point she fell back into the tub with a splash, laughing uncontrollably.
