Take a pack of someone's cigarettes, and carefully remove partial contents from a few of them. In one, pull out some of the tobacco with tweezers, insert a "Pop-It" (make sure it is closer to the end without the filter) and reinsert the tobacco with tweezers. I can't guarantee this method won't blow someone's face off, so try it on a dummy first. In the second cigarette, grind up a little sun-dried dog turd, and sprinkle it in before replacing the tobacco. In a third, put in a little wad of a few human hairs (these really stink when they burn). Make sure to pack the cigarette pack on your knee or a table, to get all of the tobacco back tightly in place.
