When i used to work at an automotive shop, when it wasnt busy... We cleared out everything in the middle of the shop and put a trashcan in the middle, than we bundled up some seat covers and floor mat covers we put in the cars when we brought them in a kinda made a ball out em.
Then we preceded to play horse lol. but it was EXTREME horse. We would stand on top of some of the lifts and raise them in the air and shoot from there, or shoot from behind the service desk, haha good times.
We also took a big torque wrench and attempted to play baseball.
