Comedian and actor Billy Crystal had been close friends with Muhammad Ali for many years, beginning with his appearance at an event honoring the legendary boxer in 1974. That moment — featured on ABC — helped launch Crystal’s career, and the comedian and boxer remained friends until Ali passed away last week. A special service was held for Ali last night in Louisville, Kentucky, where Crystal spoke at length about his dearly departed friend, delivering a eulogy that was equal parts heartwarming and humorous.
