Be it an act of self defense, a reaction to trauma, an explanation for humans regarding a fantastic sapient species
, a Running Gag
or a Blatant Lie
; the body will do crazy things. A limb falls off. The heart shuts down but doesn't kill the person. The persone is immune to something basic like intense cold or heat. Things you just cannot explain in the anatomical sense (especially if the person's nonhuman). Unless you give that glorious reason. It's a medical condition. Once you say it, there's no need to look into it. You might need to go to the hospital, sure, but no one needs to know why this happens.
It just is.
- In the Star Trek: The Next Generation episode "First Contact", Riker plays a strange human version when he visits an alien hospital. He explains to doctors that his human anatomy is a congenital condition.
- In Star Trek, Kirk and Spock must explain the latter's ears in the episode "The City on the Edge of Forever".
Kirk: My friend is obviously Chinese. I see you've noticed the ears. They're actually easy to explain.
Spock: Perhaps the unfortunate accident I had as a child?
Kirk: The unfortunate accident he had as a child. He caught his head in a mechanical... rice picker.
- The Forever Knight character Nick says he works the night shift and is never seen eating because of light sensitivity and food allergies. In truth, he is subject to vampirism.
- Sam and Fuzzy once had Fuzzy (who is a teddy bear-like creature) pass himself off as "a little person with hypertrichosis and Acute Ursus Facial Syndrome" and became a national television star. Before he became famous, he managed to get by with no explanation at all.
- In the show Invader Zim, Zim explains his green pigmentation is the result of a skin condition.
- The 2011 film Rio had the bulldog Luiz constantly slobering. Jewel points this out, thinking Luiz wants to eat Blu. Luiz doesn't want to eat the parrot, it's just said trope.
- The Adventure Time episode "Jake vs. Me-Mow" had Wildberry Princess explode her body into a bunch of smaller pieces to prevent an attack from Me-Mow, leading to the latter's "death". She explains afterwards to Finn and Jake that she's not naked. It's just a medical condition and she painfully walks off with the two to find a hospital.
