Many years ago when I was in the Air Force, my buddy and I would work out right after work and have a huge post workout meal afterwards. Anyway, we walk in the Base gym and the place is crowded - much more so than usual. We grab the 1st bench thats available. Not even into our second set, , this gas-like (gas, as in fart) odor begins to permeate the entire gym. People begin to step out side, ya know, as if they are taking a break? Well before ya know, practically the entire gym is outdoors. Looked like a fire drill!! I don't think anyone got in a good workout that evening. Some people dared not to re-enter the premises for the rest of the evening. We gave up after the chest workout as the odor's aftermath continued to linger. We knew our workout was destroyed and decided to call it an early night. The next time we were in the gym, everyone was talking and laughing about it. We never found out who the farter was but that was the meanest fart I've ever encountered! One of the guys started joking about how he thought that Iran may have launched a chemical warfare attack or something.
