In one of the podcasts that I listened to, I heard about this new AI-generated George Carlin special: I'm Glad I'm Dead. 

As a fan of George Carlin, I had to listen to it, even though I knew it was fake. The situation is a bit unclear. The Carlin estate sued the producer, and the details are hard to come by. The uploader says that most probably the jokes were written by a human, and probably, just the voice was generated. 

Regardless, I think it's a cool achievement, despite not really feeling as good as a Carlin show.
