Doctor's prescription ......

Cleaning out my office today, I came across something I had forgotten about:

"A printer went to his doctor for a checkup. The physician wrote out a prescription in his normal handwriting. The printer put it in his wallet and neglected to have it filled. Every morning for two years, he showed it to the conductor as a railroad pass. Twice it got him into Radio City Music Hall, once into a baseball park, and once into a symphony concert. One day he mislaid it at home and his daughter picked it up, played it on the harp and won a scholarship to a music conservatory." Author unknown
