A young woman wasn't feeling well, and asked
one her co-workers to recommend a physician.
"I know a great one in the city, but he is very
expensive. Five hundred dollars for the first visit,
and one hundred dollars for each one after that."

The woman went to the doctor's office and,
trying to save a little money, cheerily announced.
"I'm back!"

Not fooled for a second, the doctor quickly
examined her and said, "Very good, just continue
the treatment I prescribed on your last visit."
