I had a drum that was stored on a huge wardrobe and was pretty unstable. One day, as i opened the wardrobe, the drum fell on my head. I laugh about it today because fortunately, the wound was not as severe as i though at first.
Working at Dairy Queen when I was a teen. I was cleaning the soft serve machine and forgot to depressurize and drain the machine before i opened the front up. As soon as I loosened the last bolt it exploded gallons of chocolate and vanilla soft serve ice cream. In an instant, the entire mall food court was sprayed in a fine mist of soft serve. Once I wiped the ice cream from my eyes and realized what just happened, I looked around and there was a perfect outline of my silhouette on the wall behind me.
Reminds me of a guy I knew who was in the navy on a “boomer” (nuke missile) sub. The toilets on it had special pressurization systems to force the contents out into the ocean when underwater. Well you had better follow the instructions if you used them, part of which involved closing a ball valve before flushing. If you didn’t do this the pressurization would force the contents back up at the flushee resulting in “blowing shitters”. Since you had to clean up your own mess nobody made this mistake twice.
