When I was in the Army the guys used to pull the foot lockers around in a circle on the barracks floor on a saturday night after a good mess hall feed of Federal beans, turn the lights out and have a fart lighting contest.
Fart gas is largely methane and sulphur dioxide, which is flamable and burns with a blue flame. The troops would sit there telling crude jokes, zippo in hand, until the spirit moved and they would list over to one side, let it rip and touch it off producing a blue flash, muffled “pop” and commentary from his peers, who acted sort of like the judges on American Idol.
One poor Private ignited his offering a little prematurely and burned a hole through the seat of his fatigue pants as well as most of the hair around his naughty bits.
We found him in the latrine sitting in the gang urinal trying to extinguish himself - he got some second degree burns down under and was the butt of some cruel jokes for a while thereafter.
