In scientific, medical, or high security settings, X-Rays are used and may sometimes show funny and/or unusual things on the subject they are used on. In other scenarios, X-Ray Sparks can serve the same purpose. Examples include:
- Exaggeratedly large or small brains in the head, representing how smart or dumb a character is.
- Sometimes a small object may be substituted for a brain to represent a character's stupidity.
- Unusual objects in the stomach, showing that a character is an Extreme Omnivore.
- Objects up the asshole... or in other funny places.
- Objects that probably shouldn't be shown on X-Ray, probably due to being an important element of a character or Critical Research Failure.
- Very dangerous objects, usually at Checkpoint Charlie and other high security settings.
- Nothing at all, including lack of skeleton, to show something is unusual about a humanoid character.
