Answer: I'd probably rule out of the last reason you mentioned, on the first one you have to consider that the lie goes deeper than just the father's identity, if that is a lie at all. Through the information he saw on the medical record - and he kills her after seeing that record - it turns out that she had let him be abused and beaten up since a tender age, which would probably be the cause of his mental and physical issues. In his line before the murder, he mentions her full name, and how he has not been happy a minute of his whole life, so the terrible childhood, which maybe now came back to him, is a real factor. Mentioning the comedy, so a play, might also imply a sort of detachment now that he understands that it was all a lie from the beginning and she's not even his real mother (if that's what he believes).

Suggested correction: The movie blatantly shows Billy lifting her high enough above his head to impale her. It's literally right there in the scene. Additionally Linnea Quigley talks about the making of the scene in the documentary "In Search of Darkness Part II," and talks about the actor living her high above his head over and over while making the scene.

Suggested correction: How is someone being in the cast a piece of trivia? Unless it's something notable like one of an actor's earliest roles, or a final appearance, it's not really interesting enough to be considered trivia.

Answer: There's no indication that the Deltas didn't face legal ramifications from their actions at the parade, nor that Pinto didn't get in trouble (when we last see him, he's literally being chased by the mayor). The film ends at that point and, although the film provides title cards telling us what happened to the characters far in the future, we don't see the immediate aftermath.

Suggested correction: Janet wasn't real. She was a character in Jack's delirious dream. In Jack's dream, he was saying the things Janet was doing was written by Federman, and sometimes he controlled the scene. Not to mention the fact that some people only need glasses to see certain things and can see without them in other incidents or she was wearing contacts.

Suggested correction: This is during Jack's delirious dream and he wrote it that way to distract Carter who was waiting for the cable repair man. It wasn't something that was meant to be happening in real life.

Answer: 1 - Why does he dance a bunch of times in the movie? It's kinda his thing! You can see that Murray himself does little goofy dances all the time during his show and Arthur sorta seems to have taken that trait from him. 2 - I have heard that "comedy is subjective" for years and years. It is sort of a truism but it does fit, some people like a certain kind of humor that can fall completely flat for others. I am not sure if you should read some specificity about it in this movie, except for the fact that obviously he's using it to justify his own actions to the point of considering 'funny' to commit murder in the context of the perspective change when he starts considering his tragic life a whole big joke with no punchline. I don't really see in this movie a satire of show business or shock comedy, since it seems to focus on other themes (mental illness, emargination, etcetera).

Answer: 1. It's supposed to be a highly emotional moment for him, the first time he takes control of his own life. He basically celebrates that. 2. I think he is referring to Murray, or at least something in-universe. This is all of course speculative.
