Last night I got that one spec that knows how every trick is done! Even tho he's wrong all the time, he has a smug expression and keeps calling out its in your pocket, do it with my cards etc I put a penny and a pound in a specs hand in front of him and closed their hand (coin unique) and the penny vanished! 'you took it out with your other hand' he shouts. I got him to take my pulse and stopped it to shut him up, I think thats the way to deal with them, tackle them head on with something that cannot be explained, let them see the magic.

Any one else got any examples of how they deal with annoying specs?
