I saw that exact joke somewhere!!

There seem to be kinda two branches of responses– one where there’s a joke or comedian or stage routine or something with the joke being some sort of not-smart person mistaking brains for kidneys, and the other where there’s a phrase of nebulous origin that equates “kidneys” with “guts” as a stand-in for strength/fortitude/determination with a side implication of more brawn than sense.
