Okay, here's the douche story.
Years ago a friend of mine from France came to visit, and we went to Daytona Beach. She had heard about it and wanted to go there. We stayed at a really cheap hotel, and we had to ask to get the hot water turned on when we wanted to shower. It wasn't really a big deal though - if you've been to Florida at certain times of the year you probably know that hot water isn't really necessary! But we would take showers one of us after the other to simplify things.
So - we're on this crowded beach and she got up to go back to the hotel. She was about 20 feet away when she turned around and shouted, "Siobhan, I'm going to have a douche, do you want one too?"
