In another surprise performance, Louis C.K. says he was gone because 'everyone needs a break'

Comedian Louis C.K. does not appear to be deterred by the backlash to his attempted career comeback.

As first reported by the New York Post, C.K. returned to the Comedy Cellar in New York City Sunday for another surprise stand-up performance. He previously dropped by the comedy club unannounced in August, prompting complaints that patrons did not have an opportunity to choose whether they wanted to see a comedian who last fall admitted to allegations of sexual misconduct, including that he sexually harassed co-workers.

Although C.K. did not directly discuss the allegations Sunday, one source told Page Six that he seemed arrogant and made a comment to the effect of, "I've been off for a while, 'cause everyone needs a break." Another audience member confirmed to HuffPost that C.K. talked about being back after a "really long break" and also joked that not everyone is happy to see him return.

Audio released by The Hollywood Reporter shows that C.K. received a warm welcome, although The New York Times reports that there were at least two walkouts. The club has now put up a sign warning audience members that "we never know who is going to pop in" and that they are "free to leave" if someone shows up who "is not your cup of tea," in which case their check is on the house, the Times reports.
