Ron Bauer series Paul Chosse's Bar Bill Stunt #12
From the man who will tip his hat, but not his thumb!
The old "dollar bill stunt" of folding and unfolding a dollar bill to turn it upside-down gets surrealistic when the magician defies certain secret rules of Origami, which temporarily turns the carefully creased currency inside-out!
BONUS: Features Mike Powers' Inverted Bill, so you don't need a Mismade Bill.
