I was innocently doing my grocery shopping and I turned down the chip aisle, heading straight for the Doritos. Suddenly, I was gasping, coughing, and my eyes began to water. I had just walked into someone else's fart cloud. There were three or four people further down the aisle in front of me, none of whom were looking particularly guilty. Worse, there were two people coming up behind me. Damn the Doritos! Full speed ahead! I didn’t want them to think I did it!
