Every player, manager, and coach in Major League Baseball will wear a uniform number 42 during today's games, in commemoration of the Brooklyn Dodgers' Hall of Fame infielder's breaking of baseball's racial barrier 62 years ago.
Robinson's number was permanently retired from active use by all MLB teams during the inaugural Jackie Robinson Day festivities in 2004.
For whatever reason, Jackie Robinson Day always reminds me of that classic episode of Sanford and Son, in which the always-scheming Rollo gives Fred a special birthday present: a baseball autographed by Jackie Robinson.
Upon examining his gift, Fred asks his friend, "Rollo, how do you spell 'Jackie'?"
"J-A-C-K-Y," replies a confident Rollo.
"That's right," says Fred. "That's how you spell 'Jackie.' But that's not how Jackie Robinson spelled 'Jackie...' you dummy."
The moral of this story: If someone gives you an autographed baseball for Jackie Robinson Day or tries to sell you one on eBay be sure you authenticate the signature.
