Love the title.

I believe the authors are riffing off the wonderful 1970 Counterexamples in Topology[0] book. There's a minor tradition of this among the cognoscenti. The topology book is an absolute gem and very approachable if you have working familiarity with the fundamentals.

There's also π-Base which is a community-maintained extension of the book. It's pretty fun to explore.
