Call me a doubting Thomas, but I just don't trust visual confirmation... I need the tactile sense of shit in my hands to believe.
Edward, having raised two children from infancy, trust me on this one, you really don't. Imagine a pile of something having the subtle tint of vomitus from the movie Exorcist, with the added fragrance of a decaying whale carcass on a hot and humid beach, all coupled with a placid visual scene of something that would terrify the creature bursting from John Hurt's chest in Alien. And, that's when the little one's plumbing is in good working order.
I think it's more of a hipster parent humor thing :P
