I had classmate in high school that we nicknamed the farting bandit. He could rip on command. It was so bad at times he could clear a classroom. He let one go during a test and a bunch of us guys (it was an all boys college prep HS) got up yelling complaints at him. He got to go to the Dean of Men (responsible for behavior and discipline) and got suspended for the day for being disruptive to the class. Dad came back the next day with note from the family physician saying that it was a hereditary condition and he would eventually outgrow it.

That must have been some massive bean burrito he had for lunch.
A lighter will take care of this issue... and also convert the methane into safer chemicals for the air too.
