In this video, Mickey explains his retention vanish.

Quote from coinvanish :

One guy I have to mention is Mickey Silver (great name for coin magic).  Mickey was out at the bar performing his "Human Slot Machine" which I have to admit is one of the most hilarious things I have ever seen with coins.  He literally spills coins from his eyes, nose, mouth, ears, and rapid succession with coins clanging loudly against the table.  It really sounds like a slot machine.  He also would pass coins from one ear to another and into his mouth – it looked fabulous.  Many guys roared with laughter watching him perform this bit.
