Hawkeye always referred to Colonel Potter by his rank or his last name ("Colonel, I need some help here" or "Ah, Colonel Potter, you're just in time for Happy Hour"), while he tended to call Lt. Col. Henry Blake by his given name. At first, I thought it was primarily because Hawkeye and Blake were more friends than officers. Then it hit - Hawkeye also had far more respect for Potter than he had for Blake (probably because Potter didn't put up with much from Hawkeye). The only time Hawkeye called Potter by his given name was when he was going to ask Potter to stay in Korea... and it came out like he was asking a loved one not to leave. I have no doubt that Hawkeye loved Henry Blake, but he respected Potter - and using Potter's rank was his way of showing it.
It's not all one-way, either. Potter actually thought of himself as a Colonel first, a doctor second. He'd have told Hawkeye off if he'd gotten too casual with him. Blake was a reluctant commander who preferred not to be reminded of his rank or administrative duties when among his medical colleagues: doctor first, Colonel second (or third, if "drinking buddy" was also applicable).
And this dynamic is inverted, naturally, with Frank Burns. Hawkeye et al. clearly didn't routinely address him by his first name from a sense of chummy cameraderie.
On that note, they typically call Winchester "Charles" as both a rejection of military protocol and as a way of acknowledging that they view him as an equal. Ironically, Winchester likely takes that as an insult, since his Blue Blood makes him think he's superior to them
All the characters who disappear without explanation were in a frontline unit in a war zone, with a mine field nearby. In fact, one nurse near the end of the series dies after stepping on a mine while on a walk. These characters could have died, and it was too depressing for the main characters to mention close friends and colleagues dying. The nurse late in the series had only been there about a month, and no one had gotten to know her, and Henry dying was so much of a shock that they couldn't help but think of it.
A less depressing alternative is that they were either transferred to another unit or managed to get discharged and sent home. Since the nurses had the highest attrition rate in the show's run, a reasonable theory would be that some got pregnant from the large amount of sex being had at the 4077, while others were able to simply get enough points to be discharged.
This explanation might be an excellent case of fridge logic. Under the points system, the Army had a lot of trouble retaining experienced officers because they were naturally the ones who accumulated the most rotation points. This was especially true of Medical Corps officers, and the number of points a nurse needed to be discharged was significantly lower than a surgeon needed.
The Points system was never available to doctors, and all medical personnel starting December 1, 1945. By Korea, Points were long gone. The real reason it was difficult to retain officers was that their requirement - 80 - was lower than the enlisted - 85 - and was lowered further after VJ Day. This is partly why it was discontinued.
Or, they were disciplined for adultery and/or fraternization (a serious - and strictly enforced - offence, then and today, punishible by the UCMJ under Article 134), and were dishonourably discharged.
Since Hawkeye makes reference to an increase in points in one episode, MASH seems to take place in a universe where the point system was maintained for draftees, despite being discontinued in Real Life. The other ideas all seem to hold water.
A discarded early plotline had Hawkeye impregnating two nurses and trying to avoid marrying either one.
Rewatching the early seasons, there are a lot of nurses that cycle through the camp on short stays (usually long enough for Hawkeye to attempt to bed them, then leave). Aside from that, many nurses request transfers after a short time (this was back before Margaret's famous "cup of coffee" speech when she routinely treated the nurses like they were nothing to her, coupled with Frank's infamous mintreatement of the nurses [he once put a nurse on report for giving him the instrument he had requested]). Henry even complains that one batch of transfer requests had three nurses simultaneously requesting to leave.
Edward Winter, known for portraying Colonel Samuel Flagg, first appeared as a Captain Halloran, an officer with the CID in the episode Deal Me Out, where he played poker with Sidney Freedman. When Colonel Flagg later met Sidney Freedman in the episode "Quo Vadis, Captain Chandler" he remarked that they once played poker together.
Particularly good, as when he first appears as Colonel Flagg, a G2 officer shows up investigating him and tells Hawkeye and Trapper John that Flagg had previously infiltrated the CID.
And now I note the brilliance of the character's name - Samuel Flagg, as in Uncle Sam.
In the episode "Margaret's Engagement", Houlihan compares her new fiance to Frank Burns thusly, and this troper didn't catch the Getting Crap Past the Radar of that last example until several years later:
Margaret: "I'll always have a soft spot for a real patriot. But when I can have Adonis, why bother with Pinocchio? When I can have hewn oak, why do I need stucco? When I can have knockwurst, why settle for a..."
Hawkeye: "...a cocktail frank?"
Margaret mentions her father was dead, yet he shows up alive and well later on in the series. Maybe she meant he was dead to her in the metaphorical sense, since their relationship was rather distant when he shows up.
Why did Trapper and BJ get discharged before Hawkeye? The MASH universe maintains the points system used in World War II (in Real Life this system was discontinued long before the Korean War). Under that system, married men received extra points from the get-go (and men with children got even more) so as to allow them to return to their families sooner while still fulfilling their draft obligations. Also, BJ was shown to have gotten at least one medal during his time at the 4077. Awards were often worth discharge points, especially one as prestigious as the one that BJ got.
Frank was right about Donald. Not in a 100% specific sense, but he did tell Margaret that Donald might not be on the level. Sure enough, look at the end result of that marriage...
He wasn't the only one. When Margaret shows Potter a picture of him, he asks who the girl in the picture is.
Margaret: I think she's his cousin.
Potter: Huh, close family.
When BJ strays, he nearly writes his wife and confesses until Hawkeye talks him into simply acknowledging his mistake and not letting it harm his wife. Why does Hawkeye get so vehement in the process? Because Hawkeye has seen the damage that hurting your significant other can cause, as we find out that his long-term girlfriend (whom he acknowledged as the only woman he ever really loved) left him because he was so involved with his work.
The episode "Comrades In Arms (Part I)" opens with Hawkeye and B.J. singing opera (badly), which leads to this exchange:
Charles: Do you realize you are both singing entirely different operas and they are both out of tune?
Hawkeye: Well, don't blame me. I didn't write this stuff.
Here's the Brilliance - the screen credit less than fifteen seconds prior was Written By Alan Alda. So he did write it!
In "The Novocaine Mutiny", Frank says that he's aware that the hearing he brought against Hawkeye will result in Hawk's death "or worse", which is followed by a joke about wanting virginity. So Frank, who has entries in Unintentionally Sympathetic, was willing to see Hawkeye raped? Huh.
It was BJ and Hawkeye that were making the rape joke:
Frank: I understand okay. Death...or worse.
Hawkeye (to B.J.): Besides my life, Frank wants my virginity.
B.J.: We all do.
Hawkeye: If only I'd known.
On the other hand, knowing how gung-ho Frank is, he might just mean a dishonorable discharge, which to him would be a Fate Worse than Death.
Whenever Hawkeye replaces Frank's gun with a toy or a gun shaped lighter, he immediately pulls the trigger when unholstering it, thinking it is a real gun. We all know Frank failed gun safety and Rule of Funny notwithstanding, he's pointing it at someone every time. In Five O'Clock Charlie, when he 'arrests' Henry and Pierce for sabotaging his AA gun, he points the toy popgun at Trapper and pulls the trigger, if only done for the 'bang' flag to pop out. When he builds a small sandbag bunker in the Swamp and is woken up in the middle of the night, he points the lighter in Hawkeye and BJ's direction. Again, this was done so the lighter would light, but still. In either time, had he had a real gun and done that, he would have shot Pierce in the face
In fairness, a real loaded pistol is heavier than a lighter/toy gun. It's possible that Burns pulled the trigger after realizing he'd been pranked. Then again, this is Frank we're talking about....
In reality, it was a double-dose of research failure. They cast the role of Spearchucker based on the character from the movie, then were informed that there were no black surgeons in Korea. After cutting the role from the series, they were informed that there actually were a few black surgeons in Korea.
Hawkeye and Trapper John accidentally caused Henry's death by convincing him to return to command of the 4077th. Had they not done so, he would have completed his military service in Tokyo and never been on the plane he died in.
If one of the camp's four doctors was hopelessly incompetent, how did they have a 97% survival rate?
I believe Hawkeye would say that Frank is responsible for the other 3%.
But given the volume of patients they regularly had, and only had four doctors, they could not have such a high success rate if one of those doctors, who shared in about 25% of the load, was totally incompetent, and killed more patients than he saved.
Not all the doctors perform surgery all the time. One has to man triage, for example.
But not every time. Throughout Frank's stay, all four doctors are shown in the OR at once the majority of the time, with Frank rarely doing triage.
Not all wartime injuries are life-threatening. They probably had a lot of lesser injuries and illnesses to treat, that would account for most of that 97%; we just don't see these less-serious cases very often because they're less dramatic than the life-or-death ones.
Henry, in an early episode, tells Frank that Pierce is a better surgeon "when the heat is on." Most likely, Frank is a qualified surgeon in his own right (before he got Flanderized, at least) but he can't keep his cool when he has to hurry, like when they are overwhelmed with patients. As long as he can take his time and go by the book, Frank will have a successful operation, but drops the ball when having to do 'meatball surgery'.
In at least one episode, someone states that Frank handles the simpler operations, so he gets less chances to screw up.
He may be incompetent but not lethally so. So he can perform the needed work but not to the standard of the others, so he may leave excessive scarring, maybe nick an organ or mess something up while working ina way that negatively impacts the patient in a way that doesn't kill them.
Not to mention that we rarely hear about what happens to the casualties once they've left the camp, but there's no reason that the doctors couldn't have gotten word from the 121st Evac that one of their patients didn't make it. Who's to say that several of Frank's patients don't croak at the evac hospital?
The series is never entirely clear on whether Frank is wasting his true talent as a butcher or if he is fairly competent surgeon, though still nowhere near as good as the others, and they are just making fun of that fact. We really only have their word for Frank being terrible. He easily gets stressed and snaps at the nurses when he gets flustered and asks for the wrong instrument. He prioritize american soldiers over all others, no matter the severity of the injuries, due to a strict interpretation of guidelines and on at least one occasion he nearly cut out the last kidney of a patient because he didn't look at the X-ray. But the camp still has a very high survival-rate, so he must at least be keeping his patients alive.
One story has Potter and Klinger bartering with a Canadian unit for curare, an anesthetic banned by US officials. The unit they dealt with was the Princess Patricia's Light Infantry, an Alberta regiment. So what was an infantry regiment doing with surgical anesthetic? There were two Canadian medical units in Korea at the time, the No. 25 Canadian Field Ambulance and No. 37 Field Ambulance, yet the writers chose the most prolific Canadian infantry regiment.
They probably just wanted to use a unit name that Americans might recognize, but it also suggests a possible bit of fridge horror: since in the real world, curare was a weapon long before it was a medicine, and an infantry regiment would have no medical reason to keep a supply of a powerful paralytic, were the Canadian Forces involved in secret chemical warfare?
The episode (as do many others others) illustrates that anything of value could be put on the trading block between units. It's entirely plausible that the Canadian unit had taken in the curare in a previous trade, knowing it had high value to a medical unit.
The irony being that Charles almost kills a patient with curare early on, but is the first to tout its effectiveness in trained hands like theirs.
Which brings on even more Fridge Logic, since Charles would have likely studied everything he could about curare so he could avoid that mistake again in the future, meaning he'd be likely to know more about it than the others.
While Charles did mishandle the curare, the error was mistaking it for morphine when he was trying to relieve severe pain in a post-surgical patient rather than in how he used it for its intended purpose. (While he erred in not properly verifying the label of the drug he was about to administer, someone also made an equally serious error in putting a vial of a drug only useful in surgery in the ready drugs tray of the post-op ward. Such a drug should only be out for use in pre-op or the OR itself.)
That raises the question of why it was there to be misplaced in the first place. The US Army never approved its use to begin with (which makes the comment in the other episode that high command banned its use inaccurate).
How was the jeweler in "Patient 4077" able to reproduce Margret's ring, down to the size and the font and type of the engraving, that she only notices it's a fake because it says "Over Hill Over Dale, Our Love Will Ever Fail", if he's never seen it?
It was implied that Donald had bought her a cheap ring of the same design to give to her, and a ring size is easy enough to find out about a person (especially if Margaret had filed any sort of lost property paperwork). As for the font, it was probably wrong as well, given how quickly her eye was drawn to the inscription after Klinger gave the fake to her. A change in font, especially on a ring you didn't have very long, can be written off as a trick of memory, but the dropped letter was the giveaway.
Klinger is a deserter. Despite Potter not swearing him in, Klinger did sign a reenlistment contract, and the Army isn't likely to let someone out of it because they signed in the heat of the moment. By staying in Korea, and (assuming After MASH was a thing) later returning to Toledo, he should have been arrested on sight.
Couldn't Potter—or even Klinger, himself—simply have "misplaced" the document before it was sent up the line to I-Corps?
Not likely. The recruiter had the paperwork with him when he left, so odds are that it was processed even before Klinger's "Corporal Godiva" routine.
