Former WBST staff announcer David Letterman, who was awarded the Mark Twain Prize for American Humor on Sunday, says he will donate the award to his alma mater, Ball State.  Letterman said he was humbled by the award.  WISH-TV reports Letterman went on to say, “It is going to my college, Ball State University. We will let my son take a look at it, let him get it all fingered up with Cheetos and send it to Muncie, Indiana.”
