Sounds like a fun game!I like to do it by myself on elevators. It's kind of like a stinky game of Russian Roulette.....the excitement/anxiety/adrenaline/relief you feel as each floor passes and the doors don't open....it's awesome. Of course, I never see the fall out of my flatulence because if the elevator stops, the doors open and someone gets on...I automatically get off and take the steps....but I imagine the tension of standing with someone in my stink cloud; almost daring them to say something would be off the charts awesome.
