I was out performing street magic the other day and you know how it is when you get a guy who, if he sees something suspicious, he decides to shout it out to the crowd. Well I pulled this guy out the crowd and asked him if he wants a trick performed on him. " as long as you don't cut me in half." chuckle chuckle. Was his reply. Anyway, so i started to perform a few card tricks and as I did I stole his watch, pen, bracelet and chain around his neck. Then I pretended to do a card trick wrong and he laughed at me so I said outloud to the crowd. "He may laugh now but he wont be laughing when he realises these are missing." at that point i produced the goods and the look on his face was unbelievable.
So if you have a heckler on your hand. Just pickpocket him/her.
Well that sounds pretty good, but for those who want to pickpocket them, make sure he isn't going to get mad that you stole his stuff, and make sure you pracitce on friends and family first.
