Continuity mistake: When Mulcahy is describing a person who was "quite a Bozo" to Potter, Potter realizes who he is referring to. Mulcahy's arm is close to the table. When the camera cuts to Mulcahy's face, his mug is close to his face.
Continuity mistake: When Potter is chewing out Klinger about the morning reports, the camera is looking at Potter. As he finishes his line with "once in a while", he puts his right arm down. When the camera cuts to look at Klinger from behind Potter, his (Potter's) arm is up and finger pointing at Klinger.
Other mistake: Rosie says she took the darts away from Klinger and BJ, but there are still plenty of darts sticking in and around the dartboard. (00:12:45)
Suggested correction: Rosie said she took them away AFTER they began throwing them at the dartboard. Therefore there would be some in and around the dartboard. And since Klinger and BJ were drunk, they likely wouldn't have thought to grab them from the board.
When we later see them in Col. Potter's office, they are quite capable of semi-coherent reasoning, so them not realizing they could grab more darts from the dartboard isn't really in sync with that later behoviour.
