Time Magazine declared it the Best Comedy Sketch of the 20th Century, a recording has been placed in the Library of Congress's National Recording Registry, the line "Who's on First?" was included on the American Film Institute's list of 100 memorable movie quotations, and a video of the "Who's on First" scene, taken from The Naughty Nineties, plays continuously on screens at the Baseball Hall of Fame in Cooperstown. Unless you've been living under a rock for the last three-quarters of a century, you know the famous Abbott and Costello bit. I bet you can even recite part of it.
But I didn't realize this until I went looking for the video. We know almost the entire roster, except one player. The name of the right fielder is never identified.
