Ones that I've done:
-Wire-tied a spring to a guys toolbox drawer on the inside so that when he pulled it open it it slammed it back shut. That took awhile but was worth it.
-Same guy I put his toolbox on blocks so that the wheels were barely off the floor. He gives it a yank to move it and doesn't go anywhere
. I come in the next night and my box is on blocks with the wheels off.
-One guy had his shop-issued brass putty knifes neatly placed in a screwdriver holder. The handles opposite each other with the blades against each other. I swapped them out with two that I JB Welded the blades together. The look on his face when they both came out together.
Another time I swapped his pack of cigarettes in the top till with a pack i had put in the shop press and ran up to fifty tons. I should mention he was an old hippie and a had a little too much fun back in the day.(RIP, Touhey)
Ones done to me:
-Had the top drawer of my box FILLED with plastic resin pellets (about the size of grains of wheat)on top of the small hand tools. That was right up to the edge of the line but he was a friend so I just reminded him I knew how to weld and had all of third shift to mess with his box.
-It was real common while I was working on a mold in the press and not watching my back to get a blast from a fire extinguisher in the ass, be wire-tied to the tiebar, or my my frayed jeans set on fire.
Just plain wrong:
-Had a guy who was a helluva moldmaker but had some issues. One time he put a dead bird in a guys box just before a long weekend. Another time he put some of his own feces in a small plactic squirt bottle and would sneak up behind someone and "puff" some of that nasty air in their face. Kharma and a substance problem are catching up that guy.
