Broken Ace: Dr Anthony Borelli is an experienced frontline surgeon from both World Wars. In spite of his experience, or maybe because of it, he was just not ready to return to the life of a frontline medical unit.
Broken Pedestal: Hawkeye is left sadly unimpressed when he comes to the Swamp towards the end of the episode and finds Borelli has been drinking just before an important, delicate and new form of surgery only the veteran doctor has experience with.
Hawkeye tells Borelli when they first meet that if he wants to know about doctoring near the frontline, he should be working at a MASH unit or an aid station. It backfires when Borelli responds that he's already served as a frontline doctor in World War One ... and Two.
Hawkeye justifiably does it again after Borelli drinks before a transplant surgery and he had to serve Borelli's role in the procedure to cover for him. However, he becomes too judgemental and proud of his own ability to stave off the want to drink that Borelli reverses it on him.
Borelli: You have a great many gifts, Doctor. It's a pity you can't number compassion in among them. I'm suffering from the three sure signs of age; bit of a spread, grey hair, feet of clay. I wish you better luck on your third war.
Cassandra Truth: Charlie Company does not believe Radar when he insists that he is calling from a hospital.
When Henry Blake arrives to escort Hawkeye and Trapper to the helipad for their official trip to Japan, Hawkeye informs him very funnily that Trapper isn't ready. An unamused Henry tells him to can it.
Hawkeye adds on to Henry's recommendation to Dr Borelli that the unit's mess tent is a good place to eat.
Hawkeye: The tent is terrific. The food puts you away.
Oh, Crap!: After returning to the 4077th with the artery required for the transplant, Hawkeye tells Radar to get Borelli for the operation. The company clerk comes back to him with bad news.
Precision F-Strike: Trapper's response to seeing Dr Borelli arriving at the 4077th by chopper.
Trapper: I'll be damned.
Professional Butt-Kisser: It does not take long after Borelli's arrival for Frank and Margaret to start acting like sycophants.
Running Gag: Radar drives up to the administration office and meets Colonel Blake. He is then told to drive over to the Swamp. What he failed to recognise was that Henry meant for him to drive them both there, leaving Henry to walk. He does this again when Hawkeye and Trapper depart for Tokyo and leaves Henry behind at the helicopter landing pad.
Hawkeye and Trapper treat their visit to Tokyo like a holiday rather than the official function it's meant to serve as.
Frank Burns cares more about avoiding legal trouble than using a new medical technique that's been proven to work to save a patient from having his leg amputated.
Stiff Upper Lip: Major Taylor believes the 4077th is raising too much fuss over a soldier losing a leg, going on to tell Hawkeye and Trapper that his own father lost both legs and keeps to this trope regardless.
