This ones a little harder to do, but we managed to pull it off. Our parking lot at work is basically the woods with cleared spaces to park. One of our guides is the king of pranks, so we set our sights on him.
While he was out on the riverr we lifted the back end if his tiny sports car and put a lock of wood under the rear differential. The block of wood made it so his rear tires were an Inch off the ground. Being in the woods it was easy to hide that with leaves and debris. When he got back and went to leave we all hunkered down behind a gazebo as we tried to contain our excitement and laughter as he put it in gear and tried to leave but went nowhere. I guess you had to be there as we were literally rolling on the ground outta sight as he jumped out hands in the air thinking something was majorly wrong with his car. When he caught sight if us on the ground it was priceless!!
