When Hawkeye is dancing with Dish he called Margaret Hot Lips. Later when Margaret enters the party with Frank the general says Hot Lips both Hawkeye and Trapper look at each other as if they had never heard her called that before. Hawkeye and Trapper are probably just surprised to learn that Margaret and the general were "familiar" enough with each other for him to call her Hotlips.
When Trapper hits his tee shot in the opening scene, Hawkeye goes to play. However, when the scene changes back, Trapper is hitting instead.
Hawkeye in another episode after a bug out won't go into a cave because he is claustrophobic yet in this episode he is seen hiding in both Dish's footlocker and duffel.

Walter "Radar" O'Reilly is portrayed by an actor (Gary Burghoff) who has a noticeably deformed left hand. The US military will not accept either volunteers (nor draftees during selective service) who cannot hold, nor accurately fire, a weapon.
Additionally, O'Reilly deformity clearly would prevent him from completing many of the physical exercises required during US Army basic training as well as during AIT. He would not have been selected for service.
When Frank grabs the still, it is obvious that it is a copper-coil type still, but when he throws it to the floor, the sound of breaking glass/ceramic can be heard.
