FARTTTT...."67!"
FARTTT..."66!"
Good thing it was just a fart and not one of those times when you fart so hard you actually break the seal and poo yourself. A controlled dump. Like those times when you just get your underwear down in time to sit on the toilet seat as it rushes out of your ass and makes a giant "ploop" sound.
