The first American prime time television episode to feature male nudity when Radar lost his towel running from the sniper in the shower revealing his bare butt.
When the North Korean soldier starts shooting at the camp and Henry and Radar are in the shower, Henry says the unit is completely unarmed.
Not true, because in many shows you see Klinger or other soldiers on guard with M-1 Garands as well as .45 cal semiautomatic pistols, which the officers can carry, seemingly if they choose to, when they go to the front. They also have a contingent of armed Military Police.
The only episode where the dart board isn't on the door of the swamp.
