Continuity mistake: Season 5-19, Episode: His Story III. While Carla and Turk are lying in bed at the start both of them keep changing positions between shots. Turk's left arm and hand also keep changing position between shots.
Plot hole: Season 5, episode 20 (My Lunch). One of Dr. Cox' patients needs a heart valve transplanted. Heart valves don't have to be transplanted from another person. They can be replaced by a metal valve, or the surgeon can create a new valve from a different part of the patient's body. There was no reason to wait for a donor valve when they had other options available.
Plot hole: In the season 5 episode "My Fallen Idol", it is a key plot point that Turk has a hard time hugging guys. However in the Season 3 episode "My American Girl" Turk openly gives another surgeon a hug after J.D. makes fun of him. It is not possible for him to have changed because it shows that even before they became doctors, Turk would not hug J.D.
Character mistake: In season 5, My Transition, Kim mentions that on her 1st ever 1st date, she sat in the back seat of her boyfriend's Miata, but that car is a 2 seater - there is no back seat.
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: Dr. Cox's hair colour and length change back and forth significantly during the episode.
Continuity mistake: S6-E01. When Perry is lecturing the interns, the sweat stains on his shirt change between shots. For example, when we first see him there is no sweat around the collar, but in close-ups there is sweat around the collar.
Continuity mistake: In series 6, episode 1 ('My Mirror Image'), the length of Dr Cox's hair fluctuates noticeably between scenes.
Continuity mistake: When JD gets hit by the blue paint and confetti by the Blue Man Group at their concert, most confetti in the next scene disappears and JD is almost covered only by paint.
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.
My Best Friend's Baby's Baby and My Baby's Baby - S6-E2
Continuity mistake: When Jack asks Perry what is on the screen, Perry's arm moves from the back of the sofa to his lap in an instant cut.
My Best Friend's Baby's Baby and My Baby's Baby - S6-E2
Continuity mistake: When Turk goes into the room with the camcorder on the tripod, the viewer is already open from the front. However when it goes into the back shot of Turk to show Carla, the viewer is shut again. Then it goes to the front view of Turk and the camcorder, it's open again without anyone touching it.
Revealing mistake: Watch the line appear on the wall as Kelso cuts through the wall into the "Luxury Suite." The line is being cut with a round, drywall cutting bit such as would be used with a drill or Dremel tool. You can see it spinning as the cut is made. However, when Kelso has pushed down the wall and points the tool at Cox and the Janitor, he is now holding a standard reciprocating saw with a flat blade which would cut very differently than what was shown.
My Musical - S6-E6
Continuity mistake: Carla and Turk's song and dance, "For The Last Time I'm Dominican", was filmed a couple of months later than the rest of the episode because actress Judy Reyes, who plays Carla, was recovering from a broken hip at the original time of shooting. Stephanie D'Abruzzo, who played the patient, was brought back in to film the scene; her hair is noticeably longer during the "Dominican" song than during the rest of the episode.
My Musical - S6-E6
Continuity mistake: The EMT on the right of the screen has his hand on his hip, then on the trolley in an instant cut.
His Story IV - S6-E7
Visible crew/equipment: When Slagathor is watching Laverne, Dr Cox and Elliot and Turk argue amongst themselves, you can see just under Slagathor's feet the tape she is standing on to tell her where to stand during filming. (00:11:20)
Continuity mistake: When the janitor falls out of the moving van (having just woken up and not realising it was moving), we see him hit the ground and roll a number of times. By the end of the shot, his head is almost touching the roadside fence. However, when the shot changes to get a close-up on his face, he is some distance away from the fence.
Continuity mistake: When Turk marks the location for the surgery on Pvt. Dancer, he makes a horizontal mark on the left side of Dancer's abdomen. You can also see a small scar on Dancer's right side opposite the mark. A couple of shots later, Dancer is shown from the front and the mark has now switched to the right side above the scar.
Answer: Dan was drinking beer and Cox feared that Dan might get so intoxicated he would fall asleep and drown in the tub.
