Corrected entry: Hawkeye gives the nurse an order of one quarter gram of morphine (250mg) for a soldier. That dose if given by IV, which is almost always how drugs were dispensed in MASH units and specifically on that show, would almost certainly kill him. There is no way Hawkeye with his talent and expertise wouldn't make absolutely certain that he would have made clear it was to be given orally, and more relevant is he simply would not order morphine, "by the gram."
Corrected entry: To avoid being the last victim of the jokes, Hawkeye sets his bed up in the compound, surrounding it with barbed wire. Trouble is, the wire is wrapped in such a way as it would be impossible to him get over or through without getting cut to shreds.
Corrected entry: Hawkeye and B.J. buy Margaret a new ring in place of the one mistakenly thrown out by Klinger. The peddler says, "Cheap setting, miracle glue". Cyanoacrylate glues were first discovered during WWII but were not commercially developed, as it was thought their quality of sticking to everything was a nuisance. It was rediscovered during the 50s but was not sold until 1958, five years after the end of the war. The second mistake is on this site: the episode was not called "Patient 4077," but "Patent 4077."
Corrected entry: Trapper John and Hawkeye have a gin still in the Swamp. Distilling gin requires a constant supply of freshwater, large amounts of juniper berries, coriander (and other flavourings), magnesium carbonate, and potassium carbonate. Burnt alum and pipe clay are needed for filtering. Where do they manage to find these things in war-torn Korea in the Fifties?
Corrected entry: Unless the regulations for the time period were different, the belt buckles seen with the regular fatigues is incorrect. They should be the same color as the belt and/or uniform. The brass buckles seen were used with the dress uniforms only. Also, any rank insignia worn by officers would have been dull in color so that they would be less of a target to snipers.
Corrected entry: In the scene where Hawkeye and BJ are actually fighting while pretending to fight; when they enter the tent, Frank is polishing his boots and whistling the theme music to The Muppet Show (1976). While The Muppet Show had already been screening for a year when this episode was first broadcast, the music was unknown in the 1950s as it was written specifically for the show by Muppets creator Jim Henson, and Sam Pottle.
