What we're dealing with: 1,500 inmates of the Cebu Provincial Detention and Rehabilitation Center, Cebu, Philippines, all in their orange suits (except for the transvestite who plays the terrorized young woman) performing a choreographed dance to "Thriller."
Accuracy of the parody: 5. (Although parody in this case does not seem like the right word--something about the prisoners' grim faces during the performance makes it seem this was not exactly "fun" for them). The dance moves aren't lifted directly from the video, but they are performed with such precision it somehow seems that they must have been.
Worth watching: Uh yes. If you haven't yet watched this video, we cannot consider you a full-fledged member of the greater body of Internet users.
