Gruesome Reality

When you look at something a bit too well, you can see how it'd play out horribly in reality. For a good example, slapstick. If most of the heavy slapstick gags that go on in the movie or TV shows actually happened in real life, the person being subjected to them would be seriously injured or maybe even sent to their grave.

This is a well-played instance of Comparing Real Life To Fiction where you take something that happens in fiction, look at it from a realistic point, and see how horrible it'd be to have occur in reality.
