Two reasons to love Vin Scully

One, from his Wikipedia entry:

On Saturday, June 3, 1989, Scully was doing the play-by-play for the NBC Game of the Week in St. Louis, where the Cardinals beat the Chicago Cubs in 10 innings. Meanwhile, Dodgers were playing a series in Houston and Scully flew to Houston to be on hand to call the Sunday game of the series. However, the Saturday night game between the teams was going into extra innings when Scully arrived at Houston, so he went to the Astrodome instead of his hotel. He picked up the play-by-play, helping to relieve the other Dodger announcers, who were doing both television and radio, and broadcast the final 13 innings (after already calling 10 innings in St. Louis), as the game went 22 innings. He broadcast 23 innings in one day in two different cities.

And secondly, for an example of his work doing play-by-play, the final inning of Sandy Koufax's September 9, 1965 perfect game is available here (mp3).
