Morgan Spurlock - "30 days" - 2006 - NSFW

Spurlock is a documentary filmmaker. He had an interesting series where he would place people in different environment and cultures for 30 days (ie had a gay and straight person be roommates for 30 days, atheist/believer). I didn't see this episode but I would hazard a guess Morgan went to jail for 30 days. To his credit he filmed the strip/shower scene to show the lack of privacy prisoners need to become accustomed to.
