Continuity mistake: While J.D. and Carla are visiting Mrs Wilks near the start she has a tray of food and a bit of paper next to the tray in front of her.

Continuity mistake: When J.D. walks up to the table where his interns are sitting, Keith and Rex are fighting with their table knives and have them crossed. The shot switches to a view from the other end of the table and suddenly Rex's knife is on the table and he is facing J.D. but Keith's knife is up in the air as if he was still fighting with Rex. There is not enough time for Rex to put his knife down and turn to face J.D.
Continuity mistake: Season 5-24, Episode: My Transition (1). The first time we see J.D. and the flyer about his deck, the flyer has a picture of J.D. looking straight ahead smiling and the writing on it reads "Old? Gay? Like Decks?" After J.D. rips the flyer off and shows it to the janitor, the picture of J.D. has changed to him giving a thumbs up and the writing has also changed to "Come and Chill at my big gay deck."
Continuity mistake: After J.D.and Julie take their picture with the old people masks and have taken them off, there are a lot of pieces from the mask still on their face.

Continuity mistake: In the intro, JD comes running back into the shot after trying to change out of the same exact outfit Dr Cox is wearing. JD has the "Baby Gap" TShirt stuck & wrapped around his head turban style. The shot switches to over his shoulder and the shirt is now loose, like a towel wrapped around his head.
Continuity mistake: As JD is unwrapping the patients head while talking to the Janitor, he completely unwraps the gauze and there is 3-4 inches of hair showing. The shot changes and suddenly the head has gauze on it again and only about an inch of hair is visible above the bandage.
Continuity mistake: When JD is in the wheelchair talking to Dr Cox and he almost tells him he was a gymnast in high school, a female doctor in a white coat is walking in his direction behind him. One shot later she's gone, and a few shots after that she's back walking in the same direction. (00:02:55)
