Louis C.K. unexpectedly returned to the stage Sunday night at the Comedy Cellar, where a new policy has been instituted to address patrons uncomfortable with drop-in acts. The performance came just five weeks after his first unannounced appearance there set off broad controversy: could he be aiming for a comeback, less than a year after he admitted to sexual misconduct with women in the comedy world?

In the performance on Sunday, according to audience reports, he did not address his inappropriate behavior, including instances in which he masturbated in front of multiple women. He took the stage just before 10:30 p.m., and, working from notes, did about 20 minutes of material. There was wild applause when the host announced him, and a warm send-off when he left. “You’ve been very kind, thank you very, very much,” the comedian said from the stage.

One audience member visiting from Europe said the crowd was happy to see him and laughed. But some in the audience were made uncomfortable by jokes he told about his daughter, according to HuffPost. And two women walked out on the act, the club said.

It was Louis C.K.’s first time there since Aug. 26, the same day he did an unannounced set at Governor’s Comedy Club in Levittown on Long Island.
