I have a friend in the area that is also a magician that is pretty good with a muscle pass. Tonight, we just happened to show up in the same line at a local pizza establishment. The guy behind him looked like a perfect target so I walked up to my friend, acted like I didn't really know him and pulled out my Irish Penny and asked if he'd ever seen one of these. He caught on pretty quickly to what I was trying to do and said, "Let me see."
At which point I muscle passed it to his waiting hand. The guy's eyes blinked several times and nearly fell out of his head when my friend muscle passed it back to my waiting hand. The guy spoke up and asked to see the coin. I said, "Sure!" and pulled a Cornelius coin-falling-up routine and handed it to him. He tossed the coin several times and handed it back to me confused (him, not the coin). :pepper:
I proceeded to pass it up to my accomplice's hand and then he passed it back to me. I did my horizontal pass from behind the spectator right in front of his face and finished off with my Coin-to-Watch finale. The guy nearly passed out and my friend (who had not seen my coin to watch before) was left dumbfounded as well.
Totally impromptu and and it was great!!! :righton:
