On a Saturday evening, a couple of guys were out mudding in their personal trucks. One truck got stuck badly in some mud with the consistency of Elmer's glue. The second truck tried to pull it out and ended up equally mired.
Someone had keys to the work truck which had a winch on the front. They brought the work truck out to the stuck trucks, now in the middle of the night, and freed them using the winch. The trucks were so stuck that even the winch struggled, and blew out. When told to rewind, it limped back to a position approximating being rewound but the cable was a mess and clearly the winch was toast.
The work truck was taken to a self-service truck wash and everyone present hosed all of the mud off it, leaving it immaculately clean. The truck and keys were returned to their proper spots.
On Monday morning, everyone went to work and was shocked (shocked!) to find out that somehow, mysteriously, the winch on the truck was in bad shape and needed to be replaced. The boss was suspicious but decided not to ask questions he didn't want answered.
