Comedian Louis C.K. performed on the ‘Late Show With David Letterman’ last night for the first time in 15 years after being banned from the show for a never-explained reason.

During an interview with GQ magazine in May, C.K., who once wrote jokes for David Letterman, said he was no longer welcome at the ‘Late Show’ and wasn’t entirely sure why. But shortly after the interview, the comedian was confirmed as a guest on the show.

C.K. marked his return with a killer set covering his kids and how inconsiderate people should be eaten by lions in order to further human evolution.

Check out the clip below, as well as C.K.’s first Letterman set from 1995:
