Muhammad Ali's memorial service was filled with stories about the champ in and outside of the ring.
Billy Crystal was a close friend and told the packed arena in Louisville about the first time they met ... and how Ali reacted to Crystal's impression of him.
Many, many others spoke during the nearly 4-hour long ceremony. A scruffy Crystal joked, "I was clean shaven when this started."
Ali's widow, Lonnie ... 3 of his daughters ... Sen. Orrin Hatch and Bryant Gumbel also shared their memories.
President Bill Clinton delivered the final eulogy of the memorial .
