Himself?

From 1965 to 1968 I worked for Sinclair Refining Company, the office staff of the warehouse. This morning I thought of Jenny, the secretary. She was a hoot, and in a way my hero. I remember one time a racing car crew head mechanic called wanting a certain product that he believed they needed for the racing car they were fixing up. We did not have it and told him it would take weeks to receive it. He evidently told his boss, the car racer and he called us back and Jenny answered the phone and he told her his famous name and added “Himself”. Jenny broke out laughing and said something like, “What can I do for you Mr. Himself?” I forgot if Jenny worked wonders and got the product to him in record time or not.
