Continuity mistake: During the scene where the class is being warned about the dangers of being a "wait and see" type of doctor, JD imagines himself as being the only person in the auditorium. In the first shot of him alone, there is a bookbag (or something similar) sitting on a seat about three seats to JD's left. In the next shot of him, it is gone, and in the third and final shot of him alone, it is back again.Guy
Continuity mistake: When J.D lends his nasal spray to Doug in the final scene Doug returns the spray to J.D after putting the cap back on. In the very next shot as J.D says "Don't bogart my nasal spray", J.D uses the spray without putting on the cap, and you can see the cap placed on Doug's tray.
Character mistake: Throughout the series, JD and Turk are shown to be major sitcom geeks. At one point in the episode, JD says to Turk he Marcia Brady'd his ass, and explains what it means. Turk responds along the lines of "Yea, I know. 'Marcia Gets Creamed' Season 5 episode 3. Don't ever question me about The Bunch!" 'Marcia Gets Creamed' is season 5 episode 10. Episode 3 is 'The Elopement'. Not a mistake a couple of geeks would make.Rlvlk
