Bottom Line Gents: It's cool to think this is true, but there is no solid proof.
I choose to doubt unless proven true.
As to outside, unreferenced consultants having been used: I've said all I will. Believe or don't
"Reality TV" is far from it.
Take the Osbournes for example. This is how an episode is constructed:
1) The show uses interns to examine hours of raw footage, recording time of day, room of house, participants, basic conversation
2) Show writers brainstorm plot ideas
3) Video clips are pulled to splice together "What happened"
So, a given aired conversation may really be comprised of things that happened Monday, Wednesday, and Sunday.
BTW: It's quite sad how much footage must be viewed to find Ozzy saying something coherent.
Real bottom line: These shows are entertainment, nothing more.
