Shut Up, Scary Thing!

You shut the goddamn hell up, super monsters.

—Black Mage, Kind of a Raw Deal

Someone is talking, either to someone else or to the viewer. But slowly, creeping up on them, is a horrible monster or villain. You know this person's gonna die. Or they're in serious trouble. The monster begins to roar...

And the person turns around and says, "oh, be quiet." And the scary thing actually does.

This is a comedic trope used to create a sharp contrast between the large, mean looking thing and the considerably smaller person who tells it to shut up. This often takes the form of someone who's talking being interrupted by an intimidating, powerful looking beast, but also sometimes is done by having a little guy have a friend or pet or relative who's muscular, huge, and intimidating, but can easily be calmed just by being told, "be quiet."

In some cases, this can happen because the person telling the big scary thing to be quiet doesn't realize it's a big scary thing... yet.

Examples of Shut Up, Scary Thing! include:
