Fresh perspective, not so fresh water

In order to get Eli to stop drinking his bath water, I was forced to tell him that it was gross booty water.  After all, who really wants to be drinking water their bare butt has been soaking in?  I bet he just hadn't thought about it like that.  That's why it is always good to bring another perspective...  maybe we are all drinking booty water of some sort or another, and we just need someone to open our eyes to it (and close our mouths).
