The accountant finished, zipped up and started washing and literally scrubbing his hands...clear up to his elbows....he used about 20 paper towels before he finished. He turned to the other two men and commented,
        "I graduated from the University of Michigan and they taught us to be clean."

The lawyer finished, zipped up and quickly wet the tips of his fingers, grabbed one paper towel and commented,
        "I graduated from the University of California and they taught us to be
          environmentally conscious."

The cowboy zipped up and as he was walking out the door said,
        "I graduated from the University of Texas and they taught us not to pee on
         our hands."
