Mayhap it's time to resurrect this thread for a bit.
Here's a good one where the moral of the story is that you always get what's coming to you, and it usually happens in the most hilarious and humiliating fashion. The summer of '99, I was working as a fueler and ramp-rat at Burke Lakefront airport in Cleveland. The job paid the bills because flight instructing sure wasn't cutting it. There were four of us on the 7 to 3 shift: myself, a new trainee named Kevin, a veteran fueler named Steve-o, and the line manager Rob.
Rob was one of those types that believed that he was the be all and end all, and that he shouldn't be bothered with trivial things like... work. He was also very quick to point out your flaws and would not even have the decency to look in your direction when he refused your desperate pleadings for help with that ramp full of biz jets during game 6 of the playoffs and the Indians were winning. I'd locked horns with him a time or two, and for the record yes I really do think he needs to have a boot broken off in his arse (long story).
Anywhat, I was in the hangar doing some upkeep on one of the tugs. Kevin and Rob were squatting beneath a Falcon 900 owned by a very eccentric and somewhat senile Cleveland bazillionaire (he was an owner of the San Jose Sharks at the time, and had the team logo painted on the tail). This particular Falcon had two distinct "chambers" inside the cabin. The front was where the galley and fore lav were, and was the place that the crew got to call home on extended trips. The rear was the private stateroom and aft lav for the owner, and let me just say that his taste in movies was rather interesting. I know this because after one flight he'd forgotten to put away his collection of Swedish bondage massage films. Rob was in the process of showing Kevin how to work the Crapillac Poop-DeVille, our affectionate name for the lav cart, by servicing the aft lav.
I'd serviced the aft lav on this plane before, and I knew that the cap for the dump valve was a bit gimpy. It took some doing to get it to come off because some bozo in the past at some other FBO had cross-threaded it. Rob popped open the access door and wrestled with the cap trying to get it off. It wouldn't budge no matter how he twisted and heaved and argued with it, so he improvised. He went to the nearby tool rack and got a flat head screwdriver and a rubber mallet, the proceeded to beat the cap into submission to by trying to chisel and pry it off. I put down my quart of oil and sat on the tug, eagerly awaiting the show that I knew was coming soon.
The cap finally budged enough to come loose, and now it could be turned by hand. Rob happened to be directly under the thing and started loosening it. He looked up at Kevin and uttered the immortal words "Now, make sure you're not directly under this thing when you take the cap off. There might be a suprise waiting behind it." Kevin nodded, and with a final twist of the wrist Rob freed the valve cap.
Now, I'm guessing that all of that banging and prying and chiseling with the screwdriver and mallet was not well received by the innards of the lav dumping system. Apparently, the vibrations and the impacts were enough to knock the dump valve open. Rob was looking up at the panel to see what he was doing, and he was greeted right in the face by 4 and a half gallons of chunky bluish-green foulness that I don't really care to imagine. Kevin got off easy because his shoes were the only casualties, but Rob was drenched from head to toe in the stuff. He got up slowly, like a zombie rising from the grave in a George Romero flick, and started walking very stiffly through the hangar. He barked an order at me to open the door for him and follow him to the janitor closet where I proceeded to dump bleach and hot water on him to wash off the filth. He then excused himself to go home and get changed, and we didn't see him again the rest of the day. Steve-o missed the entire crap-tastrophe because he was on the ramp fueling a jet, but he shared a hearty laugh with us as he helped us clean up the mess.
True, it was a filthy mess, but it came to be in such a rewarding fashion for the three of us.
