Continuity mistake: The text with the symptoms written on the board changes several times, watch the letter F on the left. Sometimes it has a line across it, sometimes not.
Continuity mistake: When House is talking to Luke about the Vitamin K deficiency and eating the hamburger, the lid on the ketchup bottle is closed on the shots facing House and open on the shots facing Luke.
Continuity mistake: 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.
Continuity mistake: Chase is 26 years old in season one. In season two he's 30.
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: Season 6 - Ep. 6 Known Unknowns Before House goes to the hotel he's out on the street and the collar of his shirt is up during all front and back angles, except for a brief single back angle where it's down. Then it changes to up again.
Continuity mistake: Dr. House is listening to a patient's heart with a stethoscope. However as the shot cuts to his face you can see the stethoscope is not in his ears.
Factual error: In episode 414, "Living the Dream," the patient Evan is given a nerve function test. We see Kutner and Taub performing the test by puncturing Evan's legs with needles. Modern nerve function tests actually rely on electrical impulses from a small computerized device, with no needles necessary.
Suggested correction: House ordered an EMG (electromyography) to test for motor nerve entrapment. During an EMG, one or more small needles (electrodes) are inserted through the skin into the muscle. The electrical activity picked up by the electrodes is then displayed on an oscilloscope. An audio amplifier is used so the activity can be heard. When an electrode is inserted, a brief period of activity can be seen on the oscilloscope, but after that, no signal should be present.
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: 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.
Revealing mistake: Exactly ten minutes to the end, the couple with the baby Maxine are waiting to hear how she is doing. The mom and the husband are sitting on a bench outside the room in which their daughter is being treated. The mom lies down on her husband. She is supposed to have given birth only recently, so she still has a big tummy. As she lies against her husband, however, it is clear that she is wearing a prosthetic stomach: her blue T-shirt tucks and crinkles into and around it in a way that shows it is not an organic part of her.
Plot hole: When Wilson does an ultrasound to check for cancer in Alex' ovaries he fails to notice the fact that she doesn't have a uterus. If he mistook her bladder for her uterus, which sometimes happens, she would have appeared to be missing her bladder instead. Yet Wilson doesn't pick up on anything being missing.
Role Model - S1-E17
Continuity mistake: House puts down his Gameboy with the cover up and reaches for his vicodin. A couple of seconds of Foreman looking at House and the shot returns to House, as he is still getting his pills, but now the Gameboy's cover is down.
Other mistake: House has Metroid Hunters on the DS next to the gangster's ear and it shows Samus in a ball rolling around. The way she was rolling couldn't have been achieved because House was holding it, his fingers nowhere near the buttons on the game.
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)
Continuity mistake: The first baby dies on December 2nd. House's clinic patient is four months pregnant, and is given an expected due date in late March. Her due date would actually be in early May, if she's in her fourth month in early December.
Failure to Communicate - S2-E10
Continuity mistake: 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, and in the next it's gone. It switches back and forth throughout the rest of the scene.
Here Kitty - S5-E18
Continuity mistake: House spews cranberry juice all over the right side of Kutner's lab coat. In the next shot, the red stains have disappeared from the coat and are now on his shirt.
