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.

Continuity mistake: When Elliot goes to the bus depot to stop Shawn from leaving, she jumps out of the car leaving the car door open. When she's on the phone with Shawn, the car is behind her and the car door is closed. As the bus pulls away, the car door is open again. (00:19:30 - 00:20:25)
Deliberate mistake: When Carla shows Elliot what she looks like in the bedpan and Elliot says she looks like Alice Cooper, you can see her reflection in the bedpan. However the camera is to the side of Elliot's head, so if we can see her reflection, she wouldn't be able to.
My Best Friend's Wedding - S3-E22
Audio problem: If you look at the band's mouthes in the back round, they are completely out of sync with the song for a verse. (00:19:05)

My Best Friend's Wedding - S3-E22
Continuity mistake: As JD and Turk are walking away from the camera as they are playing the golf game in the hospital car park, Turk is wearing a white visor in the front shot, but not in the behind shot. It's not hidden behind JD's arm either.
Audio problem: When Turk comes in to tell everyone that Dr. Kelso has ruptured his eardrums, Dr. Cox starts to say, "Bob you stupid mother..." from the back view. Then it cuts to a different camera angle, and he is mouthing the words, "stupid mother" again.
Continuity mistake: Dr. Casey's sandwich has a red topped tooth pick in it, but disappears from the sandwich in next shot to the side of his plate without seeing him taking it out. (00:12:45)
Continuity mistake: The amount in Dr. Miller's drink changes inconsistently throughout the scene with Dr. Kelso and Dr. Cox. (00:06:50 - 00:08:15)

In the next (long) shot, when it is revealed to be a police cruiser, there is a cage between them and the camera. This cage disappears again in the next close shot.
Visible crew/equipment: When Ted walks past J.D. and the Janitor you can see the mic on top in middle of screen. (00:09:05)
Continuity mistake: When J.D. marks on the wall, Its not the same mark when the Janitor says "You drew on the wall" the second time. The first mark has a curve near the top, The second one bends in the middle. (00:01:10)
