My Own Private Practice Guy - S2-E17
Continuity mistake: When Laverne does a slam dunk, you can see that the ramp leading to the hospital main entrance has no-one standing on it or in front of it. But before and after the slam dunk you see see two doctors with a basketball on the ramp, and Franklin standing remarkably still, with a camera, in front of it.
My Way or the Highway - S1-E20
Continuity mistake: In the first scene when JD is playing with the pin art, you can see that his eye sockets have made an impression in the pins. Cut to the close up, and the eye area is completely flat.
Continuity mistake: Laverne's soda can goes from being on her notepad to on the table between shots.

Visible crew/equipment: When JD and the Janitor are having a conversation outside the hospital, on the giant X, crew members are reflected in JD's helmet when the camera is facing the Janitor.
My Catalyst - S3-E12

Other mistake: When J.D. is walking towards the hospital on his last day, it's actually the same shot of him walking towards the hospital on his first day. (00:01:40)
My New Role - S8-E7
Audio problem: Season 8, episode 7 "My New Role": Before the opening credits, JD taps a pencil against a cup, and other various devices in the hospital start making a song. At the end of this song, the Janitor can be seen playing the bongo. The rhythm of his hands do not match the rhythm of the bongo sounds at all. After the song ends, JD turns to the Janitor, who is again playing the bongo. This time, however, his rhythm of his hands do match up with the rhythm of the bongo sounds.

Continuity mistake: When Dr. Fisher stands up from being tackled by Dr. Cox, his stethoscope is outside his collar. When he turns around, his stethoscope is now completely hidden by his coat collar.
My New Suit - S5-E18
Continuity mistake: As JD is unwrapping the patients head while talking to the Janitor, he completely unwraps the gauze and there is 3-4 inches of hair showing. The shot changes and suddenly the head has gauze on it again and only about an inch of hair is visible above the bandage.
Factual error: In the scene where J.D goes to Elliot's apartment and finds Dan there he sings along to "Thank you" by Dido. However that song is from the album "No Angel". The album cover shown in the episode is "Life for rent" which doesn't feature the song.
Continuity mistake: While Kim is holding the baby for the first time, she has her right hand under the baby. When JD asks if he can hold the baby, her right hand has moved and is holding the baby's head.
Other mistake: When the Janitor plays with Kelso 'double or nothing' for tossing the cotton ball a second time in the jar, Todd tells Kelso he now owes him $600, in the end it was $700. This isn't a 'double or nothing' amount of money the Janitor could generate. They started with $5, so the count would be 5 - 10 - 20 - 40 - 80 - 160 - 320 - 640 - 1280 and so on.
Answer: No, it was a fake, they used a stamp.
It is real.
