I am a bricklayer by trade and i sure have seen some classic stitch up's and abit of friendly banter on the jobsite over the years. weather it be trying to lasso the extra stored energy out of an unplugged electrical lead before rolling it up. or one bloke i seen was challenged to a apple eating contest where the apple had been hollowed out by a nail and filled with wet cement first but the best one i have seen has to be when the apprentice was conviced that when the tempereture reached over 30 deegress he had to rub lotion on the dogs balls as they were sensitive to the sun :) . And as the heat soared he knew the time was coming he zinced up his hands and went after the dog chasing him into the corner whilst we all hid behind the brickstacks trying to hide our cries of laughter anyways here is the result ... 
no animals were harmed in the making of this i would love to see what other stitch ups you guys have been apart of
