Three mechanics were in the bathroom standing at the urinals. The first mechanic finishes and walks over to the sink to wash his hands. He then proceeds to dry his hands very carefully. He uses paper towel after paper towel and ensures that every single spot of water on his hands its dried. Turning to the other two, he says, "At Ford, we are trained to be extremely thorough." The second mechanic finishes his task at the urinal and he proceeds to wash his hands. He uses a single paper towel and makes sure that he dries his hands using every available portion of the paper towel. He turns and says, "At Chevrolet, not only are we trained to be extremely thorough, but we are also trained to be extremely efficient." The third mechanic finished and walks straight for the door, shouting over his shoulder: "At Jeep, we don't pee on our hands."
