I was watching M*A*S*H, the episode "Officer of the Day", with Hawkeye reluctantly filling in the role. Back in the clerk's station, Hawkeye wanders around with Radar dutifully helping him in his task and, seeing two enlisted personnel standing at attention with rifles slung, says:
Hawkeye: "What's with them?"
Radar: "Uh, the guard needs to be changed, Sir."
Hawkeye: "Well, change them and get them outta here." 🤣
