Hacker News doesn’t like jokes.

Or rather, if you’re going to make a joke, it had better be as part of a substantive comment that exists to do more than just tell a joke.

That wasn't a joke of the, "Why did the chicken cross the road?" sort. Satire can be used to illustrate a point, often more effectively than plain-old words; hence, the comment is no longer grayed out.

Technically only second part was intended as a joke. First part is how I honestly expect the school to take such interference.
