The metaphors usually refer to the show's patient, as the team try to figure out what's going on. House is usually the one confusing the team, but sometimes one of them rise to the challenge, like in Ep2-12: Distractions:
Cameron: His brain is like a waiter that's got too many...Only to be knocked back by House. But hey, he does them well! Like the murder scene metaphor in Ep2-19:House vs God. Simple, easy to understand, right? Well, as long as you know of the medical stuff he's referring to. But the metaphors are more interesting anyway. Some of his better ones:
House: Heyyy! I do the metaphors.
Ep1-3: Occam's RazorWilson tries to appeal to House through metaphors. Maybe it's catching. Comparing House to Moby Dick when he wouldn't stop chasing a disease in Ep2-17: All In was a classic (House wouldn't chase the whale, he'd convince it to be caught). Also great was the image of House as a cat in Ep3-14: Insensitive, when his curiosity about a Sepia patient gets the better of him. Is there a theme here? Obsessive and destructive...
House: Hey! How you all doing? Interesting fact: every seven years it's a whole new you. Inspiring metaphor, huh?
Wilson: The something else is going to melt her brain.
House: Poach. Better metaphor.
Of course, the best parts are when House confuses not only everyone watching, but the team (and Wilson) too. That moment of silence, while they figure out who's gunna bite. Some apt House-isms.
Ep2-18: Sleeping Dogs LieIt's not always Wilson who has to take the bait, but he does tend to take one for the team.
House: Great battles kick up a lot of dirt. Obscure the battlefields so the generals can't see what's going on.
Wilson: ... So what are your orders, General House?
Ep1-17: Role Model
House: You know, when the Inuit go fishing, they don't look for fish.
Wilson: ... Why, Dr. House?
House: They look for the blue heron, because there's no way to see the fish. But if there's fish, there's gonna be birds fishing.
There's so much more to show and tell about metaphors in House. But, this post is long enough. I'll visit the metaphors again.
