I dont eat there anymore, because of my health, and the fact that it makes me sick to my stomach now, but back in the 90s, I used to eat at Burger King fairly regularly, and their chicken sandwiches would often give me the most rancid gas imaginable, where I would blow farts of imcredible stench, and often.
Also, in college, I had a friend for a while, who would lie in bed with his girlfriend, blow the most digusting farts imaginable, and then intentionally pull the covers over their heads, so she could smell the fart. The girl looked positively revolted.
