An overweight blond consulted her doctor for advice. Her doctor advised her to run 10 miles a day for 30 days. This, he promised, would help her to lose up to 20 pounds.
The blond followed her doctor's advice, and after 30 days she was pleased to find that she had indeed lost 20 pounds.
She phoned her doctor to thank him for the wonderful advice that had been so effective in helping her to lose weight.
At the end of the conversation however she had one last question. "How do I get home since I am now 300 miles away?"
