Continuity: In the episode "Informed Consent" (Season Three, Episode Three), 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.

Continuity: In the episode that aired on 27 March 2008 in the UK, House has the shot glasses next to each other. Camera changes after a few seconds where you can see House's hands, and the glasses are no longer apart. Submitted by Duff "King Of Beers" Mckagan

Factual error: In the episode "Daddy's Boy", it is stated that a patient of House's collapsed while attending a frat party at Princeton University. However, Princeton does not have any fraternities or sororities.

Continuity: In Season 2, Episode 17 - "All In", the young patient goes into respiratory arrest. You see the doctors remove the pillow from underneath his head to put the breathing tube in, but in the next shot, the pillow is back.

Continuity: In Season 2 in the episode "Failure to Communicate," when the scene starts with Stacy and House in the airport about to start talking, she has a pen in her mouth. In the very next shot, it's on her ear, where it stays for the remainder of the conversation.

Continuity: Most of the time, whenever House puts down his Nintendo DS, the angle at which it is bending changes. For example, in one shot, it is not bent at all and in the next it is almost closed.
