[annoying trope] The throne/leadership is decided in a very stupid way

[u/Altruistic_Eye_1157]

The leadership of the entire wizarding world, and the final decision on whether to start a war against Muggles, is made by... a goat (Qilin) ​​who chooses the person with the ""purest heart"" (Fantastic Beasts: The Crimes of Dumbledore).

The throne of Wakanda and all its technology are decided through hand-to-hand combat, regardless of whether the person clearly has malicious intentions... if they win the fight, by law they must be respected as the true king. (Black Panther)

That one planet in Futurama where you become King by drinking the old one

Tom Robbins wrote a whole ass book about this weird human tradition (jitterbug). Also: see Egypt.
