At 35:52, House's phone rings with the "team tone." At 36:00, Taub is seen hanging up a hospital landline in an image-viewing room. It seems unlikely that House would program every hospital room's landline into his contacts and assign them the team tone, just in case.
(at around 15 mins) House and Wilson are in the cafeteria. House leans over to Wilson's plate and steals some food. He reaches into his inside pocket and takes out a fork and starts to eat. The next shot is over House's shoulder towards Wilson and you see House reaching into his pocket.
When Phineas Gage is brought up House asks if their patient has a railroad spike through his head. The Iron bar that went through Gage's head was a Tamping Iron; Very different from a railroad spike in function, shape, and size (The Tamping Iron having twice the diameter & being ~6× as long.).
