I was changing the oil at work once and the idiot that did it prior to me put hte oil nut on as tight as possible. To get leverage, I went and grabbed a larg wrench, to put the circle part around the handle of the socket wrench, thus makign the handle twice as long.
Anyways, in a rush, goijng back under the truck, I managed to loosen the bolt and drain the wrong fluid. I drained the oil for the differential oil in the front end. ooops. Boss wasn't to happy. Local shop had some a mile away though, so it was remedied quite easily, but still, I am a jacka$$.
