"Kidney Now!" is a memorable catchphrase originating from the American animated television series The Simpsons. It is primarily associated with the character Mr. Burns and his desperate plea for a replacement organ.
Origin
The phrase first appears in the episode "Homer vs. Dignity," which is the fifth episode of the twelfth season of The Simpsons, originally airing on December 3, 2000. In the episode, Mr. Burns, the wealthy but extremely frail owner of the Springfield Nuclear Power Plant, is informed by Dr. Hibbert that he is in dire need of a kidney transplant. In his typical dramatic and self-serving fashion, Mr. Burns attempts to procure a new kidney by various means.One of his methods involves a theatrical advertisement for a donor, where he stands before a crowd with a sign and emphatically cries out "Kidney Now!" while pointing at himself. This scene highlights Mr. Burns's arrogance and his belief that anything, including a life-saving organ, can be acquired through simple demand.
