Carter wouldn't perform material from the monologue for stand-up audiences because it's not what they expect to see, but, he says, the genre doesn't matter as much as the performance itself. If it's stand-up, it has to be funny. Any experienced comic knows that audiences are fickle and change from town to town, show to show, and to some extent, subject to subject.

One bit he does involves Boswell and Jesus at the Pearly Gates doing a knock-knock joke, and ends with Tony going to hell.

But the fact remains that there is still strong disagreement between the groups.
