Missing Organ YKTTW Discussion
Closely related to Shrunken Organ this is a comedy trope where a vital internal organ is missing altogether without causing ill-effect (or outright death). The most common absent organ is the brain (for stupid people) but occasionally you will hear about someone being literally heartless. As might be imagined this trope is far more likely to show up in animation but occasionally you see in live action televsion too. Compare and contrast with Shrunken Organ. See also Who Even Needs a Brain? which is where someone who already has a brain looses it but survives. A subtrope of Artistic License – Biology.
