Stock Shout-Outs

A Shout-Out that pops up in a lot of places. An oddly specific Shout Out.

Apparently multiple authors independently noticed the same detail and decided to reference it in their own story. The fact that so many authors possess such a thorough knowledge of the original story goes to show just how influential the subject of the Shout-Out is.

Stock Shout Outs differ from Stock Parodies in two ways: They aren't played for laughs (beyond the inherent in-joke-esque nature of the common reference point) and they're usually blink-and-you'll-miss-it short.

Some are so famous that they've become tropes themselves.

The Other Wiki also has more information.
