I used to believe that I fart a lot, trap all my farts in a plastic bag and then inhale them the way I did with the hellion balloons, my voice would become like Donalt Duck's voice. In fact, I used to do that at school, i.e. fart in bags and inhale the gas to impress my school mates, but obviously without any results. My voice would stay the same, but I would get a bad breath!
