The assistants who swapped places with Derren were clearly putting on an act, as I've explained before. Why would what they did not be classified as acting?
For the 23376373426th time, it doesn't matter if they were putting on an act, they were the ASSISTANTS in that experiment. They ASSISTED in making it work, they were NOT the ACOTRS/STOOGES he talks about in the disclaimer, because that was meant for the PARTICIPENTS in the show!!
Like I've said, the Youtubers realise it, the Derren forums realise it, my little cousin realises it, the others at this place here.. They all realise those people were not ACTORS/STOOGES, not the ones that Derren tlaks against in the disclaimer. ASSISTANTS, ASSITANTS, ASSITANTS!! It doesn't matter what they were doing, they were the ASSITANTS!!!! The only person I've seen having a problem with understaning that is YOU. How many times do we need to repeat that for you so that it could get to your head?!
An instant stooge doesn't have to be told what to do. You're just choosing unusual definitions so as to justify your statements. The point is that nothing mystifying is occurring if the person who at first seems to be merely the subject of a trick decides to play along and perform as the illusionist wants, even if not given explicit instructions.
It's obvious that you know nothing about magic, so please don't make a fool of yourself.
Instant stooge is someone that is being used for an effect that can only be 100% done using an instant stooge. The most famous instant stooge effect by Derren is The Lift that he does on his lecture video and also on one of his old shows. That effect can only done by using one. But the needle through arm is NOT an instant stooge routine, it can be done using anyone without them helping out or knowing how it works.. In fact, as Azraeli 5 said before, Derren already did a similar effect years ago when he stuck a needle on the back of someone's hand. Was she a stooge too?! Just because it worked for him?!
Like I've said, I saw a magician does the needle through arm with someone and it worked out great. Without stooges, instant stooges or anything else. So you don't need one for this, and even if Robbie decided to play along, it doesn't make him stooge/instant stooge because that's not the intention of the effect!! You can't suddenly take a term that is well known in the magic world and then change its meaning.
Was Robbie playing along in the middle of the effect? Maybe so, it happens sometimes at magic shows. Was he a stooge/instant stooge? NO, that's far from being the right definition.
So stop thinking you are so smart, because the joke would be on you.
