Continuity mistake: When JD is talking to Eliott in the cafeteria, his straw in his orange juice changes direction between shots.
Continuity mistake: When J.D. and Eliot go bungee jumping, they go past a large pipe, or something on the way down but, when they bounce back up, it's gone.
Continuity mistake: During the scene where the class is being warned about the dangers of being a "wait and see" type of doctor, JD imagines himself as being the only person in the auditorium. In the first shot of him alone, there is a bookbag (or something similar) sitting on a seat about three seats to JD's left. In the next shot of him, it is gone, and in the third and final shot of him alone, it is back again.
Continuity mistake: When JD jumps out of the bed in the ambulance, half the sheet is hanging on his left shoulder. Then it disappears from his shoulder and suddenly appears again.
Continuity mistake: When Elliot and her dad is at the bar and he says "It's a hell hole" his glass is on the table. When it cuts he suddenly has it in his hands.
Character mistake: Throughout the series, JD and Turk are shown to be major sitcom geeks. At one point in the episode, JD says to Turk he Marcia Brady'd his ass, and explains what it means. Turk responds along the lines of "Yea, I know. 'Marcia Gets Creamed' Season 5 episode 3. Don't ever question me about The Bunch!" 'Marcia Gets Creamed' is season 5 episode 10. Episode 3 is 'The Elopement'. Not a mistake a couple of geeks would make.
Continuity mistake: When Jordan gets to Dr. Cox's place and explains how she got pregnant she says "Oh, the bus boy, the pool boy or something boy." Dr. Cox place both his hands on his face. When it cuts he's only got his left hand on his face.

My Lucky Day - S2-E9

My Monster - S2-E10
Continuity mistake: In the scene where Turk, JD and Dr Cox are talking about women, and how many they've slept with, take a look at the items on the table in the background that Dr Cox was previously sitting on, they appear and vanish. Mainly the cup and napkin dispenser appears and disappears in between shots. (00:15:35 - 00:16:20)
Visible crew/equipment: You can see the shadow of the camera after Elliot spins around on the close up before Dr. Cox enters. (00:01:05)
Continuity mistake: When the family goes to throw Carla through the window, watch the window they throw her towards. The window is made up of at least three sections of glass, each no more than 2-3 feet wide with metal posts between sections. When the shot changes and Carla (well, the dummy of Carla) hits, the window is now only two sections, each about 5 feet wide. The easiest way to tell is watch the metal post farthest to the right. When the shot changes to outside, that post, which should now be farthest to the left, has vanished.
Continuity mistake: When Dr Cox is with Eliott and Turk, his stethoscope changes from under his coat to over it between shots.
Continuity mistake: When Turk places the ring box on Ralphy's tray it changes position between the shots.
Deliberate mistake: When the janitor pulls the plug on the phone, there would actually be nothing but dead air because the janitor just pulls the plug on the handset, not the whole phone. So they added a dial tone for comedic value. (00:22:20)
Continuity mistake: When Turk is holding the chili-dog, it changes from one handed to two handed and back between shots.
Continuity mistake: Elliot, Carla and JD are in the cafeteria, JD has an orange drink that's flat on the table with his hands around the base, the shot cuts to showing his front and the bottle is now tilted towards him with a hand around the top.
Continuity mistake: Right after Kelso thanks Cox and walks away, one earpiece of Cox's stethoscope is hooked under his coat lapel. When the shot changes to show Cox turning around, both earpieces are free and hanging lower on Cox's chest.
Continuity mistake: When Elliot is talking to Carla about Paul the clock in the background reads 15:10 but at the end of the conversation it says 15:30 even though the conversation lasted about 20 seconds.
Answer: Dan was drinking beer and Cox feared that Dan might get so intoxicated he would fall asleep and drown in the tub.
