Shower surprise

I was bathing Micah and Emily tonight. I get both of them washed and rinsed off. I grab the towel and Micah says "I go pee." Well, I don't think much of that because he always goes at the beginning of the bath. I turn around as Emily is trying to back up as far as possible. Micah is peeing on her feet. She wasn't sure if she was grossed out or if it was hilarious. BOYS!
