There’s an episode of M*A*S*H where some British officers on Christmas Day mention Boxing Day, and Potter decides it would be good for morale. He declares that the next day officers will switch places with enlisted and draftees. The first switch is Potter himself who becomes company clerk under “Colonel” Maxwell Klinger. Hilarity ensues!!
I love that M*A*S*H episode. I’ll have to hunt that one up and watch it again.
