Comedian Billy Crystal delivered a eulogy at Muhammad Ali's funeral at the KFC Yum! Center in Louisville, Kentucky on Friday afternoon.

In 1979, Crystal performed a one-man routine where he joked about representing 15 rounds in the life of Muhammad Ali and Howard Cosell.

Crystal befriended Ali after his performance and said the boxer would call him “Little Brother.”
