I performed a 2 card monte at my friends youth group. I was pretty much surrounded by everyone, was fairly nervous about angles, but was confident enough in myself considering the downtime I spent away from magic. At the start of the trick and showing the first ace to my audience member, he said, "I know how this ones done," however when I gave him the ace and allowed him to turn it around, his face went blank and he said, "Oh..." So anywhoo, I did the trick, got a great reaction from everyone. Some called me the devil, some ran outside, someone patted me on the back, and overall it was an awesome reaction.
