Watch where you toot - you never know who's packin one of our "Pocket Fart Busters" in their jacket pocket. With six different phrases, you can bust those phantom farters for every occassion. Tag those inconsiderate tooters in line at the grocery store, and flag those farters who hide in dark movie theatres. No more unanswered gas - you're busted!!
