A few years ago I was taking a cruise through the Panama Canal. It was the shakedown cruise for the line and very afforable. Well, they didn't have a lot of professional entertainers for the evenings's entertainment, part of the cost control I suppose. On one occasion, willing guests were providing the evenings' program. There was a group of approximately twelve Japanese people traveling together. They created what appeared to be a group shower. There was a makeshift showerhead; a curtain on a rope that enclosed everyone and concealed their attire or lack of. They shuffeled along singing something and commenced a mock group shower. It was hilarious.
