Revealing: When Col. Potter is in the helicopter looking for a new site for the camp, you can see landscape reflecting in the canopy. This never changes position although they're meant to be flying around.

Continuity: When the chopper carrying the soldier with the wounded back takes off, the sky is cloudy and, even accounting for the poor quality of the film, the weather looks very dull. The shot changes to show Radar, Hawkeye and Margaret watching the chopper leave and it is now bright sunshine.

Continuity: When Margaret arrives from Tokyo, BJ and Hawkeye's squashed orange disappears from the ground.

Factual error: When Col. Flagg makes everybody close their eyes when he leaves, you hear the sound of glass shattering, but the window was a thick sheet of plastic.

Factual error: While on the phone, Radar spells out BJ's father-in-law's last name, "H-A-Y-D-E-N" to which Hawkeye quips, "M-O-U-S-E" parodying the old line from the Mickey Mouse club. The M.M. club didn't air until 1955. Submitted by Bob Blumenfeld

Factual error: At the end of the episode, Hawkeye asks Sidney if he's going crazy. Sidney responds, "No. A little farshimelt perhaps, but not crazy." Farshimelt in Yiddish means spoiled, moldy. Sidney probably meant farmisht - mixed up. Submitted by Bob Blumenfeld

Factual error: 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.

Factual error: When BJ and Hawkeye go to Potter to talk about Cho Lin wanting to get married at the 4077th, Potter mentions he expects to be home in Nebraska in 16 months, three weeks and four days when they try to fool Potter about Cho Lin. Potter has always said he and his family live in Missouri, however.

Revealing: In the mess, you can see everyone has their food on metal trays and ceramic dishes. Sgt Zale, though, has his lemon pie in a polystyrene dish - so that it doesn't hurt Klinger when he gets it in the face.

Continuity: When BJ tells Hawkeye not to forget his old friends, the level of gin in BJ's glass rises.

Continuity: When Hawkeye is trying to find out whether there is anything going on between BJ and nurse Donovan, a jacket behind him disappears and the other one moves to the other side of him.

Continuity: Near the beginning, while Col. Bidwell is watching Hawkeye operate, in the closeups he is standing by the window but in the wide shots he is standing in a different part of the O.R.

Continuity: While Klinger is mending the movie, the amount of film on the two reels changes a lot between shots.

Factual error: Radar impersonates John Wayne, playing a scene from McLintock - a film which was not released until 1963, which was 10 years after the end of the Korean war.
