House

One of the surgeons takes a camera phone out of her pocket. There's no way someone could walk into an operating room with one of those in their pocket, they are teeming with bacteria.

Trivia This is the first time we learn of at least one of Cuddy's specialties: endocrinology.

Whenever the tapeworm is shown close-up, it is covered in blood. But when the camera is far away, it is much cleaner.

The amount of snow on Chase's hat, in the final dialogue scene, changes between shots.

Trivia: Diphyllobothrium latum is the longest tapeworm in the human body, averaging 10 meters in length. It is caused by eating undercooked fish. Between 50-100% of Vitamin B-12 can be absorbed by the tapeworm, causing malnutrition.

In the OR the surgeon talks about the spleen that exploded, but is operating on the right side of the abdomen. Unless Stevie has a Situs Inversus Abdominalis where the organs in the abdomen are on the other side, the spleen should be on his left. The liver is on the right side, the spleen left.

In her office, Cuddy tells House he'll get back his parking space if he manages to do his work in a wheelchair. After that Cameron meets House in the hallway and she needs to ask about the wheelchair, yet somehow right after that she knows the specifics of the deal.

In the O.R., that is not how the small intestine looks like in a human being. In a normal human it is embedded in the mesentery and it's not a long loose "rope" as seen here.

When Cameron says the wrist bone mnemonic she says "scared lovers try positions they can't handle." However, the writer or actress muffs the line as the correct mnemonic is "scared lovers try positions that they can't handle", which works to remember the bones Scaphoid, Lunate, Triquetral, Pisiform, Trapezium, Trapezoid, Capitate, and Hamate.

Trivia: The bumper sticker on the back of House's wheelchair said "I'd rather be walking."

In the scene where House goes to Wilson to find out how he should answer the girl's question the shots of Hugh Laurie with the window in the background have the front of the cane handle pointed towards him while the ones with Wilson in the background have the back of the cane under his chin.

In the last scene of the episode when House and Wilson are playing foosball and they cut to the closeup of House his scar from his bullet wound is missing.

Trivia: As in "TB or Not TB," House alludes to the movie This Is Spinal Tap with a reference to controls going up to 11.

When House goes to the doctor trying to get Vicodin, the doctor first tries to prescribe acetaminophen with codeine. House keeps fishing for the Vicodin but the doctor says he can't prescribe it because of that clinic's policy on not prescribing opiates to first time patients, but codeine is an opiate.

Dr Chase seems to have amazing powers of healing. In the scene where House presents that case of the week to his team, we see him throw the case notes folder to Chase, who has a large bruise on the left side of his chin (from when House punched him in the previous episode). The bruise is so large that it almost reaches the point of Chase's chin. The camera cuts to House then, a split second later, back to Chase. At this point we see that Chase's bruise is now miraculously half its previous size.

Trivia: In the scene where House is drinking and taking oxycodone, he is drinking Maker's Mark bourbon whiskey. He is also seen drinking Maker's Mark during the final scene of "Three Stories."

The address in House's envelope is:

Dr. Gregory House
Departament of Diagnostic Medicine
10 Burlington Boulevard
Princeton, New Jersey 08540

Omar Epps mispronounces the word "misanthropy" when referring to Dr. House, emphasizing MISS rather than ANN.

If the patient has lung cancer with bone metastasis, a routine blood test should have detected it earlier.

Trivia: This episode marks the first time that House has ever lost a bet.
