Yeah, well, it could be worse. I was on an LGW-IAH flight a few years back. I also happened to be sick as a dog, getting up & going to the bathroom as much as I could. Sure enough, sometime during the flight, the smell of something really bad began to filter through my row and lingered through the rest of the flight. Of course I was blamed. At the end of the flight, it turned out that the miscreant was a 5 year old boy in the row behind me who "forgot" to tell his dad he needed to go potty. Yup, right in the seat.

Gas is temporary. Poop is not.
