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.

Other mistake: When JD and Turk get coffee from the street vendor, Turk tips the cup at an angle which shows they are empty as it doesn't spill.

My Overkill - S2-E1
Continuity mistake: When JD is done talking with Kelso, JD is holding a file in his hands. JD says "I'm the wiz kid." and it cuts to a close-up of the Janitor wetting JD's pants, but the file is no longer in his hands.
My Overkill - S2-E1
Continuity mistake: Carla, Laverne and Dr Cox are in the restaurant, Dr Cox is in front of Carla and behind her are two hospital staff members, Carla walks away and it cuts to Dr Cox, but the two staff members have vanished.
My Overkill - S2-E1
Visible crew/equipment: When JD is thinking to himself while the characters are 'drifting through the halls', you can see the rope and trolley device that is being used to pull Carla along.

My Overkill - S2-E1
Audio problem: When JD borrows the green scrub bottoms, the guy lending them to him says "Don't stain them" but his mouth stays closed.
Continuity mistake: Laverne's clipboard changes from being held out in one shot to held close to her in another while talking to Dr. Kelso. (00:04:15)
Continuity mistake: Dr. Kelso sets his water bottle down twice while talking to Turk. (00:16:20)

Continuity mistake: At the end, when J.D. has found out he is going to Reno, he turns to gloat to the other residents, and Dr. Cox. Snoop Dog Resident appears both in the group of interns opposite Dr. Cox, as well as directly behind Dr. Cox.

Continuity mistake: When Cox asks Elliot how her patient is doing he has a cup on the table. His hand goes from holding the cup to not holding it between the shots.

Continuity mistake: When Dr. Kelso is chewing out JD, the amount of banana peel hanging out of JD's pocket changes from shot to shot.
Character mistake: JD is having problems with someone dressed in a gorilla suit, who is slightly shorter than he is. JD sees the janitor, who is considerably taller than he is, eating a banana and accuses him of being the gorilla. If the janitor were as tall as JD, maybe, but you would not confuse someone shorter than you with someone taller, regardless of costume.
Continuity mistake: Carla's about to eat a piece of steak. In the next shot she's holding her wine glass without enough time to change them. (00:19:25)
Visible crew/equipment: When Todd says "Why won't any women talk with me?" it cuts to a girl saying "Because you're slimy." You should be able to see the boom mike coming into frame above the clock on the wall.
Answer: No, it was a fake, they used a stamp.
It is real.
