I will follow him - Sister Act

EVERYONE has seen the Prison Thriller video. It still makes me laugh out loud thinking about it. And this one isn't bad.

I'm amazed that this is real or even legal, but I don't care as long as it keeps me entertained.

I have some questions:
1. What genius thought this up?
2. Who gets to choose which songs are performed?
3. Do they take requests?
4. How long does the choreography take?
5. How does one go about getting arrested in the Phillipines and end up at that prison?
