Two old-timers got together one last time last night: In his final few weeks as host of "The Late Show," David Letterman was treated to an appearance by the legendary Harry Caray.

In fact, earlier this year Ferrell was on The Late Show to talk about his spring training feat of playing 10 baseball positions in a single day.
