Audio problem: The "swoosh" as the ball goes through the net is early.
Continuity mistake: When Cleo and Mark are playing basketball, when Mark shoots for the first time Cleo is standing to the left of the hoop - when the ball hits the rim it launches off the rim to the right, but in the next shot Cleo has the ball.

Continuity mistake: While talking to Carter in her kitchen, Kerry's hand goes from on the counter to on the blender with a lid that comes from nowhere.
Character mistake: Carter tells the mother of the smallpox infected children that no one has seen smallpox for 50 years. The episode aired in 2002, WHO didn't start its global eradication of smallpox until late 1950's and the last case was reported in 1978, which is only about 20 years.
Continuity mistake: Carter is doing a nasogastric intubation on a emergency patient and suddenly the patient violently pukes blood all over Carter's medical gown, his throat and the lower part of the face, then a quick shot of the stunned nurses, and when Carter is shown again he is perfectly clean.
Post Mortem - S3-E12
Continuity mistake: When he's scuffling with the homeless man in the trauma room, Carter's stethoscope slips off his shoulders and drops to the floor. By the time Mark finds him standing outside, it's back around his neck, with no moment when he could have picked it up.
Continuity mistake: When Carter and Abby drive up to the motel that Maggie is holed up in in Oklahoma, the rental car they are driving has no front license plate. When they pull up to Abby's apartment the next evening, in the same rental car, there is a front plate on the car and the plate is from Illinois.
Continuity mistake: In the scene where Dr. Benton is getting Reese ready for day care in the staff lounge and is talking to Dr. Finch, the shot shows Reese with his left hearing aid out of his ear, hanging down then when the angle changes it shows his hearing aid back in his ear without Dr. Benton putting it back in or touching it at all. (01:33:45)
It's All in Your Head - S8-E15
Other mistake: In the opening sequence, there is an aerial shot where the camera pans over Central Park in New York City. The trees are full of leaves and some are changing color. The problem is that it is February when this episode is taking place, and the trees would have no leaves left on them.
Other mistake: At Abby and Neela's graduation, there are at least a hundred students graduating. How did they get from Lockhart to Rasgota in three names?
Continuity mistake: During the opening credits, Carol is doing desk dury and says, "Hey, you're back" to Luca and her hand with a pen in it is up in the air. But when the shot changes, her hand is lying on her stomach. These alternate positions continue for a couple of shots.
Greene with Envy (a.k.a. Lawrence of Northwestern) - S6-E3
Continuity mistake: At the beginning of the show, Randi is talking to Dr. Lawrence and is holding her neck tag on its lanyard in front of her, but as she says "Malik" and the camera shot changes, suddenly her left hand is on her waist.
Continuity mistake: Oliver, the brain tumour patient, is talking to Anna, Henry, and Carter. He has his right arm up on the bed railing - but as he says "cook", his arm is suddenly down in his lap.
Continuity mistake: Near the beginning of the show, Lucy and Roxanne are in the restaurant, and as Roxanne says "so much for that theory", we can see Lucy is holding up her book/magazine in the corner of the screen, but in the next shot it is lying flat on the table.
Answer: It was in "Chaos Theory" which is the first episode of season 9 (time code 00:13:55).
