This is the first installment of the Fortnightly Topic Challenges Rerun described here and the thirty-fifth installment of the FTCs overall, with topics suggested and voted on here. This fortnight's topic is "Restricted Title" (suggested by Sp3000) and will span from the 28th of May to the 10th of June. During this period, we will compile the list of questions with a relevant title 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!

Link to other Fortnightly Topic Challenges.

The Restricted Title topic challenge does not have a specific tag associated; instead titles must be selected from a filtered list. Due to the nature of this challenge, please add your own questions to the list below. In this challenge, the possible titles are derived from the first 1000 xkcd comic titles. The original suggestion is copied to this post for posterity.

Restricted Title

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 the first 1000 xkcd comics, filtered down to only those titles which are family-friendly and would be valid for posting as a Stack Exchange question title (≥ 15 characters). Pick any of the 297 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!

    $\begingroup$ I'm so happy that xkcd was chosen as the theme of the challenge! Also, somebody should notify Randall Munroe of this happening. $\endgroup$ Commented May 31, 2018 at 10:45
