A couple of years ago I was playing music with some friends in the Wapiti Bar (Indian name for Elk) in the little town of Gardiner just outside Yellowstone Park.

I looked over and noticed a comely young girl trying to stuff something up her ass. As it turned out, on more careful observation, she was clinching a quarter (coin) in her buttocks. She then stood over a guy laying on the floor with a beer mug balanced on his forehead. She unclinched her butt and let the coin drop, trying to get it in the mug. Several people took turns doing this, and I can only assume the loser/s had to buy drinks. Oh yeah, all the women I saw participating had trousers/jeans on - I don't think any woman with a skirt would want to take part. But it could happen...!
