While working on that ol' B-29 a few years back, we had to put quite a few cylinders on three of the four engines (the fourth engine was supposedly being overhauled). What's odd about that B-29 is that nobody really wants to work on the airframe, but they're all attracted to those sorry-stinkin' engines. Sooooo, after this one guy "insisted" that he work on the engines, I let him change those cylinders. This guy was a real jerk, but he was incredibly organized. He had every single gasket for every single cylinder (about 17 total, if I remember correctly) laid out on several tables, along with all the tools, books, etc.
Well, after about three weeks of this jack-ass fighting those engines that he once loved, he finally completed the job late one night. So, before he came in the next morning, I found a spare cylinder base gasket (which is merely a large o-ring) and strategically placed it beneath one of his "personal checklists" that he kept, and had it sticking out from beneath the clip board just enough to where he could view it when he was to clean up after his arrival to work that morning.
The look on his face was freakin' priceless when he saw that base gasket there! His upper lip got to trembling and I thought he was going to cry as he tried to figure out just which cylinder he "forgot" to put that gasket on. The most difficult part of this whole excersise was for me and two of my good buddies (and GREAT co-workers) to keep from laughing our asses off and giving up the joke. You see, this guy was scared to death to ever admit he'd made a mistake...especially to me. So, we just let him think about it for a while until we finally couldn't hold it back any further. I reckon it was about lunch time before I went over and asked him how come he hadn't gotten much done that morning...and "where did that base gasket come from???" When his lip started trembling again, we finally all fell out laughing.......well, all of us, except for him.
Dang, it's cracking me up just thinkin' about it now.
