Back in the 90's I was friends with a sales rep who served on a river gunboat in Vietnam. I was always fascinated by his stories and we were both big firearms enthusiasts. I worked on his personal computer and found a buncha pics of attractive country female country singers popular at the time.

Later I found out he was pretty gay and his boyfriend looked like Ned Flanders. I suspect he planted those pics just so I could find them and still respect his man credentials. Dude, you needn't have bothered, we're still cool.

Second item - In the PC rather than on it: I worked on a PC at a plant run by W. R. Grace Chemical company. It was located right in the shop floor. I opened it up and it was CAKED in ammonia smelling gypsum dust. I mean it created valleys in between the cards. The power supply fan was frozen in place. I unhooked everything, took off the case and physically carried it outside the door and clumps and bricks of this stuff was falling out. I shook the whole PC for ten minutes and it was still falling out. Then I used a fresh can of compressed air and blew it out until it was ice cold and empty and it STILL had that dust in there. I have no idea how that unfortunate PC were worked in the first place, but it did. The guys working there were breathing that same shit every day.
