An overweight clerk consulted the doctor for advice. The doctor advised that the clerk run 10 miles a day for 30 days. This, he promised, would burn off as much as twenty pounds.
The clerk follows the doctor's advice and, after thirty days, was pleased to note a loss of twenty pounds.
The clerk phoned the doctor and thanked him for the wonderful advice which produced such effective results. At the end of the conversation, however, there was one last question:
"How do I get home, since I'm now 300 miles away?"
