It's a play about a woman who becomes an oracle at the moment of orgasm and predicts rodeo winners. It was apparently actually written for a friend and her husband to star in, but it's been mounted variously. I went to see a production with what was almost the original cast about four years ago.

She played the woman, and he played her husband, the rodeo clown. The funny thing was that she had lost a startling amount of weight since the play was written and had to wear a fat-suit to play the main character, because it's part of the role.
