Continuity mistake: When Turk is talking to someone about the teenager getting breast implants, in the first shot you can see he is talking to someone in a a blue shirt with a stethoscope - i.e. JD. However after this shot, JD has vanished and the conversation is suddenly with Todd.
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.
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.
Continuity mistake: In episode 6-12 "My Fishbowl," the janitor waits outside a door holding a fishbowl. The door opens into the room as seen several times. You can even see that the hinges are set up to open in. When the janitor sets the fish bowl down you can see that the door has changed and opens out into the hall.
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 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.

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.

Continuity mistake: Near the end, when Elliot, Carla and Jordan are in the bar, the waitress brings them three drinks; two short, clear ones and a cosmopolitan with a lime. A few shots later, Carla is seen from the front drinking the cosmo. The next shot from behind her shows the drink instantly on the table. The drink switches instantly between her hand and the table several times in the following shots.
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.
