Once more we bring this old-timer forth but after you read this see if you can beat it for simpleness and effect.
A spectator opens a new pack of cigarettes and after examining them a cigarette is removed, marked and placed in the performer's mouth. A bill is borrowed and the spectator writes down a number and initials the bill before the performer even touches it. The bill is destroyed in a most open manner, the cigarette being lighted just before this event. The cigarette is now identified by its mark and, while still burning, is broken open and the bill is removed. When handed back, the owner is asked to identify the bill by marks and number.
