Who Are the Real National Heroes?

Every year, the winners of major sports championships are invited to the White House, presumably because they are some sort of "national heroes".  (More realistically, it's a photo op for both parties, but the photo op needs an excuse.)  It would really be more appropriate to invite people who jump onto subway tracks to save a stranger from an oncoming train.  Of course, such incidents would have to be investigated first, because unsavory types would stage such events in order to arrange a meeting with the president.
