Bathtub fun, and... not so fun

Carter has gotten really into putting his letters up on the wall in the bathtub. He asks me what each individual letter and number is. Must be why he is so good with his letters and numbers... Anyway, one night he started crying out and acting scared. He had "surprised" himself with a little "surprise." I photo-shopped it in the second picture so that no one had to be grossed out, but you get the point. I don't mean to be a mean mom but it was kind of funny. Isn't his face so sad?
