All Chiefs and No Indians

When Binghamton learns that all Chief Petty Officers are to be shipped out, he talks all the guys into taking the exam for CPO, then fixes the results to see that all of them pass. Now without a Crew, the 73 is to be scrapped, and McHale and Parker are to be reassigned. But a very determined Ensign Parker takes it upon himself to keep the 73 in business.
