I work in construction and one time we took the tools out of a millwrights bag and put a piece of 1" thick solid steel cut to fit his bag in the bottom and put all his tools back in the bag and when he went to grab it to take to his next work area he eyes about came out of his head and it about dragged his back on his ass. That bag had to weight a ton already and then we added that huge piece of steel in it, he wasnt very happy.
Another time we took one of our brother eletricians tools and carefully tied them together using jetline(the kind you blow through pipes and use to pull the rope back in), we left a few inches between tools and the last tool we tied to a rail so when he got his bag at the end of the day he walked back to the trailer and he had a line of tools on the ground from the trailer to where he was working at, that was some funny shit but I felt bad cause we were all leaving and he was picking his tools up still. He was kind of an asshole though so oh well.
I have taken the back clasp of a harness lanyard and wrapped it around rails and other things and hooked it back so when the guy or girl went to move they couldnt cause they were held back.
I have put wire ease on the inside sweatband of a persons hard hat before, the blue gooey kind not the yellow sticky kind, lol. That stuff is a PITA to get off too!
I have done the old cone head gag on people before and had it done to me a few times too. You take the little cone cups that come with the 5 gallon jugs of water for the dispensors and put a little duct tape over the top of it and very slickly put it on someones hard hat so it looks like a dunce cap point.
I have seen some messed up stuff done to peoiple who drive foreign cars to a jobsite too. One guy had his car shrinkwrapped all the way around everything, it looked like a dang package when they were done with it. Another time I seen a guys car picked up with a forklift and put in a con-ex and hidden. A whole bunch of stuff like that especially at Ford and GM plants, the car plant will have a foreign car towed if you park it in their lot..they usually have a separate lot for foreign cars to park in across the street or down the road some.
Construction workers pull alot of pranks on fellow tradesman.
