An easy way to make overly intoxicated peoples hangovers the next morning even worse is to give then any big bill and a lit cigarette and tell them to put the bill on their arm and then tell them if they can burn a hole in the dollar with it on their arm, they can have it. hilarity ensues when they keep trying to burn the dollar and every time burn their arm.
