See a stoodge has a prop.
Does that mean we can sell them on Talkmagic?
A mentalist props is anything that helps you deceive the audience, whether it's made out of flesh and bone or paper. I understand that the OP was about falsely portraying something as mentalism (rather than mentalism
being just a load of lies) but to answer the question in a board sense, mentalism is not only about lying but telling totally unbelievable lies.
The problem most people have with stooges is that they make the mistake of believing the beauty lies in the skill rather than the lie.
