Paternity: Episode 2

In re-watching Paternity, just about all the similarities I can come up with are:

When House is in the clinic with "Boy-who-sued-wolf dude", the conversation goes a bit like:
House: It's infected. With a really big hole, like you stuck a nail in it to relieve pressure
Patient: I wouldn't do that
House: Although the wound is irregular; it's not cylindrical, it's shaped like a triangle, so.... steak knife?
Patient: Wife's nail file.
So, House, do they teach you to recognize and deduce the shape of a poky thing in medical school? Or are you just channeling Holmes? (I think he's channeling Holmes. But hey, it's my job to think he's channeling Holmes.)

Also, Holmes sure as hell didn't hit on his employees/Irregulars! Score one for Victorian politeness over caustic sarcasm. (Yet the caustic rudeness is so fun!)
