Last Laugh - S6-E3
Character mistake: BJ refers to his friend Leo as colonel. He's wearing two silver bars, insignia of a captain.
Factual error: When the can of beans explodes all over Hawkeye and Hotlips, they act as though the beans are cold. In fact the beans would have been at boiling temperature as the can overheated, causing it to explode, and the two would have been burned.
Revealing mistake: When Sherwood has died on the gurney, with Roberts holding his hand, after breathing stops, you can see the bandage on his neck still jumping in time with his pulse.
Factual error: Out by The Gun, Hawkeye's Captain insignia on his garrison cap is missing the lower corner of one bar. So, it would be considered unserviceable, that is, unfit for use, and should have been replaced with a new insignia.
Revealing mistake: In Margaret's tent, while she is getting ready, if you look at the central pole you can see the cut where it is supposed to break when Frank hits it.
Factual error: In the hut with BJ, Zale, and The Moose, there's a Coleman 413E stove in the background. Trouble is, that this unit didn't appear until 1954, and the Armistice ending hostilities, ending the war, was signed July 27, 1953.
Factual error: In the Swamp, Frank is complaining about everything, and goes to grab the still. The stove it's sitting on is a Coleman model 413E camping stove, a unit not seen until 1954, and the series takes place in 1950.
Visible crew/equipment: As Col. Whiteman leave Sentry Post 1, where Klinger is, the boom mike is reflected on his helmet.
Continuity mistake: In Henry's office, the white cloth Radar has on his ears changes positions from shot to shot.
Continuity mistake: In the Swamp, Pak pulls out a stack of money, holding it by the end. In the closeup, he is holding it by the middle.
Continuity mistake: When in the Swamp, and they show Hawkeye numerous times, the door to the stove is open, then closed, then open, etc.
Revealing mistake: Potter is taking the driving part of the test, with Rizzo riding along. In the long shot, as well as looking at Klinger stumbling along, you can see the Jeep occupants are stunt doubles.
Visible crew/equipment: As the camera pans around the bed in Margaret's dream, you can see the camera man and equipment reflected. Also, when the soldiers march past, the shadow of the microphone rig plays across each one as they pass the bed.
Factual error: When the camera looks at Lt. Clark, her rank insignia is horizontal. It should set from the apex (point) of the stitching diagonally (top end toward her face).
Continuity mistake: When the pit boss is taking the rolled up 5 containing the pair of dice out of his pocket, his fingers are hiding the end toward Mulcahy. When the camera angle changes, the fingers are moved so Mulcahy can see the hidden dice.
Change Day - S6-E8
Continuity mistake: From the back, while denying Charles entry, the whistle Klinger has on flips over his left shoulder. A moment later, as Hawkeye and BJ walk up, the whistle is in front.
Dear Sigmund - S5-E7
Visible crew/equipment: As Potter is panning with the binoculars, you can see the lights, camera and crew reflected in the lens.
Hot Lips and Empty Arms - S2-E14
Other mistake: While trying to sober Margaret up, you can see Trapper's clothing wet in spots where she hung on to him in previous takes.
Continuity mistake: In Henry's office, Burns tosses the stapler toward Radar, and it flips midair. When it falls Ito the file Radar has, it flies level, that is, not twisting in the air.
Continuity mistake: As Hawkeye and Trapper leave the Swamp to watch 5 O'Clock Charlie, Hawkeye is carrying a folding chair, and Trapper has the thermos and glasses. At the show, they both have folding chairs.
