What do you get when you put a toddler in a swim diaper, throw him in the pool and add in a dad that has the incessant need to play rough, including delivering body slams (fake, mind you)?
Poo all down your shirt.
Ha ha, Daddy. It seems that swim diapers aren't meant to hold poo and when you have a man-child that refuses to tell you when he goes poo the water gets in and turns it to liquid poo. When you, dear father, flip him upside down over your head - well, I don't think I need to elaborate any further, do I?
