The other day, I found myself, for entirely innocent reasons, having a shower in a colleague’s flat. While doing so, I saw that he kept his toothbrush and toothpaste in the shower, alongside his shampoo and soap, rather than by the sink. When I had got dressed, I asked him whether he cleaned his teeth in the shower. “Doesn’t everybody?” he said. Er. No.
I once heard a radio show phone-in on this very topic, and people called in with some corkers. I particularly remember the man who thought it was normal to strip naked when he had a poo.
