When I was younger I worked as a mechanic in a car dealer. I was also working out quite heavily at the time and would finish the workout with a protein shake made with powdered pasteurized egg whites. Shortly after I started with the protein shakes I started to get real foul smelling gas even I couldn't stand, and a lot of it, but didn't make the connection. The lifts were lined up in a row of about 10. While working on the cars I farted but the smell didn't carry out the door it drifted down the line. My co-worker immediately to my left was at the parts department about 1-2 minutes later the mechanic on the other side of him said oh man, who shit themselves and put down his wrench and pulled his shirt up over his nose and walked away. The mechanic on the far side of him was laughing at the reaction of the guy before him. Then the smell got to the guy laughing at the other guy and went from laughing to oh man that's bad. He too put down his tools and walked away. I was laughing so hard I was crying. It dissipated after that but by then the damage was done. Even writing this 15 years later makes me laugh so hard I cry. They told me that If I didn't stop drinking those shakes that they were going to make me work outside. I did stop eventually.
