I'm having bad luck with gas

Today while I was taking my midterm type thing. Someone was farting. It spelled like open sewage in a closed room. It was just stagnating. I couldn't concentrate! I needed fresh air. I left as soon as I possibly could. My dogs have had gas too. My 60 pound, raw meat eating dog's farts don't smell as bad as that atrocity in class. It was the foulest thing I had experienced in a long time. Let me just tell you if you aren't totally floored, you should be.
