Plot hole: In the season 5 episode "My Fallen Idol", it is a key plot point that Turk has a hard time hugging guys.

It is not possible for him to have changed because it shows that even before they became doctors, Turk would not hug J.D.

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.
