Find some shmoe who's smoking a cigarette, is quite drunk, and who you can beat up if it came down to fisticuffs.

Bet this gent twenty dollars that you can take his pack of cigarettes, balance one cigarette on the package and flip it up into your mouth with the tip of your shoe.

They almost always say no, since they need that twenty for the next round or three. Drop the bet to ten dollars. When they still say no, drop the bet down to a nickle. They always agree, since it's worth the nickle to see the trick.

Set up his pack of ciggies, balance the lone cigarette on top of the package, then stomp down as hard as you can on the entire pack. Flip him a nickle, congratulate him, then leave.
