Continuity mistake: In the beginning of the episode you see JD walking through the hospital with a huge pile of files in his hands. He see the women with the big breasts and looks after her until he sees her butt. The camera changes to JD where he is making a face in disgust. Look at the files. A few files from the top moved and it looks like they are about the fall off. JD turns around and the next shot is again at JD after he has turned around. Look at the files again. The seemed to be in perfect order, with all the files piled neatly on top of each other.
Continuity mistake: The first time Turk and Cox are talking in the gym, watch the man on the machine behind Cox. During the first shot of Cox, the man's face is obscured by the pulley for a pull down bar. Cut to Turk then back to Cox and the pulley has moved enough so that the man's face is now visible. Cut to Turk and then back to Cox for the third time and the man's face is blocked again. The viewing angle of Cox is the same each time so it is not a camera angle difference.Guy
Continuity mistake: During the scene where Ted is explaining to Dr. Kelso about the stethoscopes being too tight, Ted is holding one in his hands. When seen from Dr. Kelso's point of view, the earpieces (white) are close together but when seen from the side they are crossed far past each other.Guy
Continuity mistake: When Carla tells Turk off the second time (for not standing up for her) she is to the right and Turk is on the left, but when she leaves she walks to the right and passes Turk as he says "You're absolutely right baby and I apologise". This is because they re-used the shot from the first version of that day where Turk was standing on the right after he stood up to Kelso.
