"The ULTIMATE bar bet."
1. Borrow a cigarette.
2. Throw it to the ceiling
3. and make it STAY THERE. It's SURREAL.
No tape, no glue, no wax, no magnets. Nothing but a borrowed cigarette. And no prep required, because your preparation is part of your presentation! In fact there's almost nothing to hide.
..and if you made a friendly wager of a drink, then this trick just paid for itself on your first performance!
