No. 2: Billy Crystal
Whether he's edited himself into the Best Picture montages, wooed us with a song and dance or analyzed the nominees ("I see white people!"), actor and comedian Billy Crystal's funny antics have won us over each time -- nine times, to be exact, between 1990 and 2012.
Crystal became such a hit with audience members and viewers that he ranks behind only actor and comedian Bob Hope when it comes to most ceremonies hosted.
His advice to newcomers? "Look like you want to be there," he said. "Be good and enjoy yourself."
Crystal was so popular that when he returned from a three-year break from hosting duties in 1997, the audience greeted him with an overwhelming standing ovation. And you could tell that Crystal was genuinely moved by the salute.
Most memorable hosting quote: "For those of you who are keeping score at home, I just want to make something very clear: Martin Scorsese, zero Oscars; Three 6 Mafia, one."
No. 1: Bob Hope
Comedian and actor Bob Hope holds the record for hosting the Oscars more than anyone else: 18 times between 1940 and 1978, 10 of those as a solo host. That's a record that's unlikely to be broken.
As a well-respected actor and comedian, Hope often joked that he should receive an Oscar "just for attending." Although Hope was never nominated for an Oscar for his performances, the Academy honored him with four honorary awards as well as the Jean Hersholt Humanitarian Award.
With his unforgettable charm and wit, Hope was able to put a smile on audience members and viewers as he made the three-hour show seem shorter.
