The story the term “iron rice bowl” comes from goes as follows: A sexy maid is hired by a noble. One day she breaks a rice bowl but because she is hot (and he is probably banging her) she isn’t fired. She breaks more and more bowls. The noble’s eventual solution to this problem is to change all the bowls in his house to iron so they couldn’t break. Therefore an iron rice bowl is a job for which there is ultimate job security irregardless of your performance.
