The wife-swap thread inspired this thinking.
I myself have never been. However, I do have a story about my brother in law. He is a surgeon. At the time he was living in Rapid City, SD. His wife came to work one day and stole him away for a date. He had no idea what they were doing. He can be a little boring, but I know it is just because of the amount of time he spends thinking about his work. Anyway, Steph, his wife, picks him up and drives down to Custer, SD, where they were filming the movie Hidalgo. They had put out a call for extras for the filming of the scene at Wounded Knee in the beginning of the movie. Once he found out what was going on, he put up a fight but in the end, his wife persuaded him to just do something different for a change. He ended up being one of the Soldiers in the scene at Wounded Knee. He was supposed to just fight over a gun with one of the indians adn keep his mouth shut. He could not help himself though and during the first take, as they were struggling over the gun, he blurts out "give me the gun" or something like that. He feels embarassed as they yell out cut and apologizes. The director tells him that it was perfect and he wants him to do it just like that now. He ended up having to sign up for the SAG and gets his little royalty check from time to time. The rest as they say is history...
After watching the movie, I told him not to quit his day job.
