Ok, so what if her favorite team loses the Superbowl and she still endorses Biden? What then? Like do they think that is her one chance to endorse a candidate?

Someone could snip out a joke and claim it was Carlin. Then the disclaimers are meaningless. This happens on the internet all the time.

Writing a comedy set (ai or not) and then having a Carlin bot read it out and then releasing it under his name is definitely crossing some major lines. I'm not sure what the legality of it is at this point, but if it is legal it shouldn't be.
