I found a hotel that put little bars of Ivory (99.4% pure) soap in the rooms. Every time I would stay there, I would bring the soap home. Having your mouth washed out with soap or having to hold one of these little hotel-sized bars in your mouth for a period of time is a nasty punishment. This was mostly used as a punishment when I said something inappropriate in public. I have to admit that it is an effective punishment that really made me watch my language!
