The lady at the front desk said that Sam Depino had ordered 1,000 of them because he liked to give away a pen each time he signed an autograph. He said the viewer liked to not only have an autograph, but had a pen to remember the event with. (Sort of like when the President of the U.S. signs an autograph and you keep the pen).
Mr. Smith, III was not happy (the quote was "had a fit") and had the pens locked up and only let them be used gradually over a period of time. (I remember that too.)
