Original Commentary
I've seen them referred to as Purple Monkey Dishwasher comics - where jokes end with random gibberish in place of a punchline. It's kinda funny the first time, but I can't see the appeal of the tenth time.

The first draft had Brisbane name other comedians, and the agent would say why they were too busy to save the world. I could either make up Hypedonian comedians (in which case the reader would wonder if this was a reference he was supposed to get and all impact would be lost) or use existing comedians (which, in addition to being meaner than I'd like to be, would require me to do extensive research into bad comedians and exactly why they suck). That got nixed real quick - Terrence

Modern Commentary
Ok, the idea that Caleb's impression of Brisbane is funnier than Brisbane actually is? That's pretty good.

And accurate, because Caleb is doing it on purpose.

That would've been a good bit to have put into Unlike Minerva, ten years prior.

The bits about comedians from Hippedown, I wrote a script before I realized that it added complexity without adding depth.

B: Why me? Why not [name1]?
1: Lacks mainstream appeal, but kids think he's hilarious.
----
B: [name2]
1: He was pretty good in [movie]
---
B: That was only because of his costars. Anybody could've been good in [movie]. What about [name3]?
1: Busy.
B: Too busy to save the world from aliens?
1: Not aliens. Flying saucers.

And if I put in any names there, your first question will be "Should I know who that is?" and the answer would be no. - Terrence
