Credit for this invention goes to Mr. Robert Thurman. Using a can of Office Duster 3 (For precision cleaning of hard-to-reach areas on computers and electronics office equipment) and your arm pit, you can create fantastic fart noises. Excellent ice-breaker for those tough job interviews or meet-your-in-laws dinners. Cracks me up everytime. I have been experimenting creating different pitches by using your arm, leg and stomach (the flabbier, the deeper the sound)
Warning: Please note that shaking the can, holding it upside-down or overuse may cause frostbite. Keep away from eyes and out of reach of children.
