All the members of the 4077th are forced by military regulations to endure a routine physical check-up. Hijinks predictably ensue, but things start becoming serious when Trapper appears to be suffering an affliction and refuses to have his. He is soon diagnosed with a duodenal ulcer, which Hawkeye tells him is enough to get him a medical discharge. The camp personnel gather together to throw Trapper the biggest farewell bash he will ever possibly know, and Frank and Margaret secretly applaud Trapper's departure since it will give them a chance to rein in Hawkeye's antics.
As the party gets underway, Radar privately conveys a message to Trapper from headquarters: instead of being discharged, he has to report in for treatment of his ulcer and then return to duty. His only choice is between being treated in Tokyo and then transferred to another unit, or being treated at the 4077th and staying there. Trapper reluctantly chooses to stay at the 4077th, only breaking the news once everyone at the party is good and drunk to soften the blow.

- Could Say It, But...: Frank's goodbye to TrapperFrank: Well, McIntyre, I guess this is it. I, uh, just wanted you to know I've always admired you, always liked you.Trapper: Thanks, Frank.Frank: But I'm glad you're going.
