This was one of the Evil Overlord list entries (or at least, an entry in one of those lists, a list like it or an addendum, etc.).
If I remember right, there it was about mirrors, and having many in the evil lair / mansion / base all turned to face the wall or covered, so that the good guys start to think the bad guy is deathly afraid of their own reflection and incorporate that into their plan to defeat evil.
Then when the good guys thrust a mirror in the bad guy’s face, they can admire their own reflection and purr something like “hmm, I need a shave” before calling in the guards.
