I still remember when i was a school boy and was told the incredulous news that ,"YOU COULD LIGHT A FART!" There are certain events that alter your world, forever. We laughed and scoffed disbelievingly, until after a few days the bearer of this amazing scientific discovery on the bus from school, dropped his pants. Lit a match, and after a little grunting and straining, 'let one rip'. And ,amazingly a little blue flame blew out. He yelled, we laughed, the girls squealed, and the world would never be the same again. It turned out the reason our intrepid 'test farter' yelled, was bacause he'd had what could be termed a blowback. This unfortunate event singed his 'ringpeice'. For the following week he couldn't sit down straight. He could sit on his left buttock, or his right, but not on both. A brave lad, a scientific pioneer, if ever there was one. He suffered to bring knowledge, enlightenment and a nasty smell to mankind.
