Other mistake: The second '15 second countdown' with Jill Tracy, just after she's been to the toilet, actually lasts 24 seconds. They slowed it down to fit more dialogue in.
My Nickname - S1-E10
Continuity mistake: In the opening scene outside the hospital, Turk's sandwich turns around in his hands between shots, then keeps changing back and forth.
My Catalyst - S3-E12
Continuity mistake: Jordan's right arm goes from holding her spoon to being folded close to her a couple of times. (00:19:20)
My Brother, Where Art Thou? - S3-E5
Continuity mistake: When Dan come in and knocks J.D to the floor, the front door is wide open. But when Turk joins the dog pile the front door is closed. (00:02:05)
My Nickname - S1-E10
Continuity mistake: When Carla says "If I wanted his ass kicked I'd do it myself" and Todd makes the cat sound, Turk has his arm on the couch behind Carla's back. When it cuts his arm is gone. He couldn't have moved it that fast.
My Bed Banter & Beyond - S1-E15
Continuity mistake: When Turk, JD and Todd are at the nurses' station, the metal file in JD's hand has the labelled side facing outwards. In the next shot as he turns around to face Carla, the plain side of the file faces outwards.
Continuity mistake: Turks cereal bowl goes from empty to full a couple of times while talking to J.D. and Danni. (00:04:35 - 00:05:20)
My Overkill - S2-E1
Continuity mistake: Right at the start, two guys to our right of Jordan nod heads and walk off to the right, the shot cuts to the table and back to Jordan and the same guys are back (and this time walk off in opposite directions).
Visible crew/equipment: During the scene where JD is fantasizing about dancing with the German patient to "99 Luft Balloons," a crew member's green-sleeved arm is momentarily visible throwing balloons into the shot.
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.
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.
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 Ocardial Infarction - S4-E13
Continuity mistake: At the end of the episode when JD sits down at the table with Elliot, who is eating, Elliot puts her fork in her bowl. When it cuts, the fork is on the tray.

Continuity mistake: When the girls are in the canteen, one shot of Jordan shows Elliot's drink in front of her, before Elliot has sat down with her tray.
My Best Friend's Baby's Baby and My Baby's Baby - S6-E2
Continuity mistake: S6-E02. When Zach Braff is talking to his girlfriend about whether or not they'll keep their baby, he says something like "I sure do," and is propping up his head with a hand. In the next shot (which continues his line of dialogue) he is suddenly no longer propping up his head.
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)
My Big Mouth - S2-E4
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.
My Journey - S3-E2
Continuity mistake: When Sean is talking to Betty the seal his arms go from being by his sides to clasped in front of him between shots.
Continuity mistake: The pen on the counter Dr. Casey used changes positions a couple of times while talking to J.D. (00:17:15)
My Old Man - S1-E19
Visible crew/equipment: When Turk and Carla are talking about the Cuban restaurant, as Carla walks away and the camera pulls back, you can see two tape markers on the floor, showing both of them where to stand. (00:12:50)
Answer: No, it was a fake, they used a stamp.
It is real.
