"You know what we did this year, you and I? We didn't host the Oscars!" Rock jokingly told Kimmel, 53.
"We sure didn't!" the late night host agreed. "It was a real weird feeling of relief to not have been involved in that, at all."
The 93rd annual Academy Awards were watched by 9.85 million viewers, accounting for a 58.3% drop from the previous year, Variety reported at the time. The ceremony was likely hampered by the continuing COVID-19 pandemic, which has largely kept audiences out of movie theaters since last March.

During his Jimmy Kimmel Live! interview, Rock — who hosted the Oscars in 2005 and 2016 —continued to joke about the lack of an emcee at this year's ceremony.
"At home, I was like a backseat driver. My father used to say, 'Brake! Brake!' I was like, 'Joke! Joke!' " Rock quipped.
"Somebody must have gone to the Oscars and said, have you ever considered subtracting all the humor from the Oscars?" said Kimmel, who hosted in 2017 and 2018.
"They did a good job, if that was what they went for!" Rock replied.

During a recent interview with PEOPLE, former Oscars host Billy Crystal spoke about why having a host for the ceremony is so important.
"To me, a show needs a host, you need a center," he said. "Let's face it, after the first 40 minutes, four out of five people have lost. By the end of the night, the winners are all backstage and you're dealing with disgruntled people who are disappointed. You want to make them feel good and the home audience to stay with the show."
