When I first heard that Billy Crystal was going to be speaking at Muhammad Ali's funeral, I was a bit surprised.  I had never seen Billy's tribute to the legend during his retirement ceremony in 1979.  It's titled "15 rounds," and it proves that Billy is the man to speak at his funeral.  Check it out here.
