Opening Day -- Third Inning

I have spent countless hours watching old videos of What's My Line, jumping from one "mystery celebrity" guest to the next, sometimes for hours at a time, taking me late into the early morning.  Perhaps because TV was in its infancy, the show was able to attract really remarkable guests, who would never today dream of appearing on a game show.  However semi-famous you might think some of the celebrities might be on things like Dancing with the Stars, no, it doesn't compare to What's My Line.  Two examples pop into mind -- Eleanor Roosevelt and Salvador Dali.  That, folks, are famous celebrities.

Here, in honor of Opening Day in baseball, is another.  Someone known for being fairly shy, just on the good side of reclusive.  Joe Dimaggio.
