At the same comedy show, Rock said the quip that offended Smith was “the nicest joke I ever told.”

Chappelle also quipped that when Smith struck Rock, not long before claiming one of Hollywood’s greatest accolades, he was acting like he was back in his hometown. “A lot of people forget who Will Smith is,” he said. “Then 10 minutes before he was about to get the biggest award… he acted like he was back in Philadelphia.”

Smith received the Oscar for Best Actor shortly after slapping Rock, who had made a joke about Smith’s wife, Jada Pinkett Smith, having a shaved head. (Pinkett Smith has alopecia.) Smith won the Oscar for his portrayal of Richard Williams, the father of Venus and Serena Williams, in King Richard. During a tearful acceptance speech, he apologized to the Academy for the slap and attempted to explain his actions, saying, “Love will make you do crazy things,” but he did not mention Rock by name.

In the days after the ceremony, Smith apologized to Rock on social media and resigned from the Academy. He also released a video addressing the controversy in greater detail in July.

At the comedy show Thursday, Rock also discussed the incident, reportedly telling the crowd that Smith “hit me over a bulls— joke, the nicest joke I ever told.”

The 57-year-old comic hasn’t spoken about the slap much, but did say last month that he was asked to host next year’s Oscars telecast and declined.

Rock was also present when Chappelle was attacked on stage at the Hollywood Bowl in Los Angeles in May.

Thursday marked the first of three U.K. shows on Chappelle and Rock’s tour. They’ll appear at London’s O2 arena next and then headline sets throughout Europe.
