In several scenes, the door to Private Brian Dancer's room opens inward to his room; however, for a few scenes - like when J.D. opens the door and sends the fishbowl sliding across the floor, the door opens outward to the hall.
The level of water in the fishbowl the Janitor is holding changes several times throughout the episode.
Private Dancer's name tape is on the wrong side of his DCU (in the US Military name is displayed on the right side, branch on the left, over the heart). It also contains his rank (E-1) rather than just his last name, which is incorrect in every branch of the US Military. The abbreviation used for his rank is also incorrect (Pvt is used by the Marine Corp, the Army uses all capitals letters for rank abbreviations, in this case PVT).
