Continuity mistake: When the family goes to throw Carla through the window, watch the window they throw her towards. The window is made up of at least three sections of glass, each no more than 2-3 feet wide with metal posts between sections. When the shot changes and Carla (well, the dummy of Carla) hits, the window is now only two sections, each about 5 feet wide. The easiest way to tell is watch the metal post farthest to the right. When the shot changes to outside, that post, which should now be farthest to the left, has vanished.Guy
Deliberate mistake: In one of the later episodes of season 2 Turk is seen being bored in surgery and checking the patient's wristwatch to see how long they have been operating. Patients are not allowed to wear jewelry or watches during surgery as there is a VERY high risk of infection and it might kill them.
