Factual error: When House is looking over his whiteboard of symptoms for the swimming patient, the symptom "Intercranial Hemorrhage" is shown on the board. However, this is an error. The correct term is "Intracranial Hemorrhage." Anything inside the head is referred to as "intra" not "inter." This is a common mistake for laypeople, however the highly trained and knowledgeable Dr. House should not have made that error. (00:31:25)
Continuity mistake: House is about to inject Ezra Powell (Joel Grey) with what is supposedly a lethal dose of morphine. In the shots where they pan out to show House addressing the room at large, the syringe is very full, almost completely. When they zoom in on House holding the syringe, it is only filled a fraction of that much - maybe a quarter to a third. This doesn't happen just once, but every time they switch between shots.
Revealing mistake: In the opening scene during the game, one of the shots of the boy is reversed. You can see that the text "Tartans" on his jersey is mirror imaged. (00:00:25)
Continuity mistake: Foreman is doing a sonogram of Mary's brain. As she comes out of her absent seizure Foreman's probe jumps from the left side of Mary's head to her right.
Continuity mistake: During the scene where Dr. Chase and Dr. Cameron are out having a drink, Cameron picks up Dr. Foreman's cell phone. Before she does she takes a drink of her soda. This drink drops the level of drink to half full. When Foreman returns a few seconds later she suddenly has a glass that is 3/4 full. There was no time for anyone to give her a refill. (00:18:55)
Trivia: In this episode the director, Bryan Singer, makes a cameo as the director of the sports documentary Hank Wiggen is starring in.

Continuity mistake: Right at the end, baby Maxine and her parents exit the elevator, probably on their way home. The lily bouquet, first held by the dad, jumps into the nurse's arm consecutive shots. (00:39:30)
Continuity mistake: Right after House has given the speech he and Wilson step outside and House removes his tie. After this his shirt collar changes between almost every shot, from being tucked in his jacket to being on the outside of it.
Continuity mistake: Max's mom, without her glasses, runs out to call the nurse after Max starts seizing. Her glasses appear when she re-enters the room. (00:28:20)
Continuity mistake: When House trips before entering his office, Taub is holding the patient's x-ray film. It is either over the folder or under it in different shots. (00:11:05)

Continuity mistake: At the start of the episode, when 13's date falls off the bed, she knocks the bedside lamp onto the floor. As 13 runs to the bedroom, the lamp is laid on its side on the bedside cabinet. As 13 bends down to attend to her date, the lamp is back on the floor. (00:01:05)
Emancipation - S5-E8

Here Kitty - S5-E18
Continuity mistake: Series 5, Episode 18, "Here Kitty": When Judy (the patient) holds the tape out for House before her bronchial attack, the way she holds it changes instantly. (00:13:45)
