Is the joke that it took me like 3 minutes to write this? If so, I think that's a bit unfair to the author. I think this is something that was at least shaped. But I feel very confident its LLM written. If it isn't LLM written, then I also think it is bad writing, but that's a separate point.

I think they were supporting you -- you had free time because you carefully evaluated whether the random story you came across was AI. The 'author' did not have free time because they asked an AI to generate a story instead of writing one theirself.
