This has to be one of the funniest stories I've ever heard. This concept is just hilarious. I don't know why but I think mooning is the most comical thing. They seem to do it all in fun. A family event, I doubt that. It could be pretty funny to see all these people mooning as you ride by in the train.

I was reading that it got out of hand and had to be stopped. I guess they could clean it up a little bit and carry on with it.
