I had that same thing happen to me but twice as much!! I was doing one of my first post-mortems (of several hundred now) on a dead fat steer at a feedyard I was working at. I didn't know to stab on the off side to let the gas out. That foamy, rotten, fermented, sour feed and chit hit me right in the chest. I had the same reaction as these guys. I laughed my ass off, the two Mexican hands I had with me they both looked at me in shock and didn't laugh. Funny stuff! Great video!!LMAO
