House. A very good INTJ.
He's not an extrovert because he doesn't tell others what he's thinking, he avoids explaining his thinking (in fact he does the roll of the eyes and the whole INTJ look that communicates "Poor poor stupid mortal" in ultra high fidelity).
He's not a P because he organises others and excuses himself. Ps are the opposite to that trend. House is always asking of others what he himself is unwilling to provide.. that is what a twisted J does.
You may also find that the man himself is an INTJ too....though now I've said it I'm going to have to go check myself.
