This is the sixteenth installment of the Monthly Topic Challenges with topics suggested and voted on here. This month's topic is "Restricted Title: xkcd 2000-2500" (suggested by Lukas Rotter) and will span from the 1st of November to the 30th of November. During this period, we will compile the list of relevant questions and post it as an answer to this question.

In the meantime, please go and propose and vote on future challenges!

Everyone have fun, and happy puzzling!

Restricted Title: xkcd 2000-2500

See this FTC and this MTC for previous xkcd challenges

Usually the title is decided upon later in the puzzle creation process, chosen to be fitting and often to provide a hint/reference. Here we're going to go the other way.

Below is a list of the titles for xkcd comics 2000-2500, filtered down to those titles which are a valid Stack Exchange question title (≥ 15 characters). Pick any of the 282 remaining titles and use it as-is (preserving case, part numbers, parenthesised words, etc.) — this will be the title of your new puzzle.

The title should make sense given the puzzle, whether that be through the puzzle's presentation, mechanics or answer. The more fitting, the better!

Don't be discouraged if you see that someone else has posted a puzzle with a title you had intended to use. If anything, it can be interesting to see what different approaches people take for the same title, should there be any collisions!
