Oh, here's one of my father's favorite horror stories:

Back in the 60's, my father had a married pair of colleagues, both doctors, who didn't believe in diapering their children because they believed it inhibited their creativity. One evening when my dad was at their house for dinner, their toddler squatted on the living room carpet and took a steaming dump. When my dad asked if they were going to clean it up, they said "No, that's his offering!"

I think I would have gone out to the bushes to hurl.
