As a kid, I listened to Phil Rizzuto do the Yankee broadcasts. He was one of the most unique announcers I ever heard. He told stories, had lots of funny nicknames, and kept you entertained throughout the game. He also always said "Holy Cow!" on a great play and called his fellow announcers "huckleberry", among other things.
He also did the play by play for Meatloaf's Paradise By The Dashboard Light, one of the great long rock songs ever.
Here's a tribute to Scooter.
