Sure, you laughed until you nearly lost bowel control each of the twenty or thirty times you watched the Cebu Provincial Detention and Rehabilitation Center's all-inmate production of "Thriller," but you probably never stopped to consider whether those 1,500 prisoners were having a good time or nothing more than "dancing monkeys" under the sway of an evil genius choreographer/warden making them perform for his own, twisted amusement. ABC News went deep behind the scenes to help you make up your mind about the issue; more importantly, they provide glimpses of the Filipino jail's previous productions of "Radio Ga Ga" and selected numbers from Sister Act. Questionable prison rehabilitation practices have never been so fabulous!
