Visible crew/equipment: When Colonel Potter and Charles exit the mess tent carrying the trays, so they can serve breakfast in bed to the winners, they split up and as Charles walks to the Swamp saying, "What a shame to have wasted all these years as a doctor," we have a great view of the boom and boom mic at the left side of the screen as it moves backwards away from Charles, outside the Swamp.
Visible crew/equipment: After Hawkeye shows the photo of his father to the North Korean, when it cuts to the shot in the Officers Club just as Klinger says, "And these players you can't tell anything," the shadow of the boom mic can be seen moving at the top, right corner of the screen.
Factual error: In this episode, the regulars receive and respond to letters from a Fourth-Grade class in Hawkeye's home town. Charles receives one from a little girl who says she's sent him a birch leaf. Unfortunately, the leaf he removes from her glassine envelope is a maple leaf. (Note: there was no indication that this was supposed to be her mistake.)
Visible crew/equipment: While Hoops Potter is going for the camp record in free throws, in overhead shots with everyone encircling the 'basketball court' - particularly right after free throw 28 and after Potter says that he feels like a sideshow freak, the boom can be seen moving around right beside the hoop's post at the top, left side of the screen.
Visible crew/equipment: While BJ, Hawkeye, and Charles are in the Swamp, when BJ starts reading the letter from the child who thinks the army is like camping out Charles takes that letter away from BJ, and just as Charles is about to sit back down the edge of the Swamp set can be seen at the top right corner of the screen.
Visible crew/equipment: After Charles confronts Choi Sung Ho about the candy, Ho explains that he sold it on the black market to buy real food, and when Ho reenters the mess tent through the side door, we can see that outside there's a director's chair, which actors also use, with something printed on its back.
Deliberate mistake: Winchester is listening on the radio to the 1951 Giants win the pennant. In the MASH series, Potter was supposed to have arrived 19 Sept. 1952, and Charles Winchester after Potter did. The Giants won the pennant during the previous year, not when Winchester was there. Also Potter, BJ and Winchester are present for New Years parties for '50-'51 and '51- '52 even though none of them arrived until late 1952.
Visible crew/equipment: In the overhead exterior shot of the compound, when Colonel Potter calls everyone's attention to the situation regarding "crackerjack corpsman" Sergeant Hutchinson, as the shot pans out we can see the boom and the boom mic at the top left corner of the screen. Then when Margaret calls on Hutchinson to come forward, the boom mic is moving around at the top of the screen, and it's still there when Klinger rides out on Sophie.
Visible crew/equipment: After Colonel Potter tells everyone in his office that he's been asked to address them about the possibility of making the army their career, the Swamp trio laugh, and when it cuts to Margaret telling the "clowns" to keep quiet, the shadow of the boom mic bounces around at the top, right side of the screen.
