McHale's Navy S03 E19 The Late Captain Binghamton

After The Captain has his annual physical exam, the guys see an opportunity to get him out of the way for a while, and 'doctor' his X-rays to make it look like he's dying. But the plan backfires, when - In an effort to go out a hero - Binghamton volunteers to lead the 73 Crew on a dangerous mission to destroy an enemy fuel dump.
