I'm a school teacher and in my first week teaching one of my pupils gave me a farting sweet - i had a double period with them so about an hour and a half later I felt my stomach start to groan as the gas built up and push its way out...I tried to hold it, but as I was writing on the board, somone was messing around behind me - i turn my head just in time to see one of the kids fire a catapult, miss who he was aiming at and hit me slap bang right on my ass! ...
I lost control of my gas and it was LOUD - The class was in stitchs!
Later I found out who gave me the gas sweet and kept him behind after the class, i was shouting at him and without feeling it coming I passed noisy gas again.
