"A stick figure is a very simple drawing of a person or animal, composed of a few lines, curves, and dots. In a stick figure, the head is represented by a circle, sometimes embellished with details such as eyes, mouth or crudely scratched-out hair. The arms, legs and torso are all represented by straight lines. Details such as hands, feet and a neck may be present or absent, and the simpler stick figures display an ambiguous emotional expression.

Graffiti of stick figures are found throughout history, often scratched with a sharp object on hard surfaces such as stone or concrete walls. Stick figures are often used in sketches for film storyboarding."

"A specialized form of Breaking the Fourth Wall. Fictional characters suddenly come to the realization that they are fictional characters living in a work of fiction. As you can imagine, this is often a terrible shock. How would you take it if you suddenly learned that you, your family, your friends, and your entire universe are all fake, and that everything you've ever said, done or thought was the product of someone else's imagination? Thus, characters who experience this trope seldom take it well. Popular in comic books and among writers who want to wax philosophical."
