If you have an interest in mentalism, then I suggest checking out some of the YT stuff on Darren Brown, Bob Cassidy, and Richard Osterlind, among others. Specifically, I think you will find the "disclaimers" used by Osterlind and Brown to be of interest.
Also, check out some back story on Banachek. He WAS studied by scientists.
I asked you, not at all rhetorically or in a confrontational manner (at least that was the intent), if you were the guest and could therefore confirm that no pre-show or stooge work was involved, would you be impressed/amazed/entertained? I ask because I am interested in your answer, not trying to prove a point one way or another.
