Here is a short explanation of why I think House is ENTP, without relying on individual anecdotes.
Judging functions = thinking and feeling
Perceiving functions = sensing and intuiting
J vs P determines whether your judging or your perceiving function is extroverted. A P always extroverts the perceiving function. That means that if we accept that House is a P (which I do), he has to have Ne or Se as his first or second function. That would mean he would have Ti or Fi as the other. I vs E determines whether your extroverted function is dominant or auxiliary. I, personally, see House as Ne-dominant, so he has to be either ENTP or ENFP. And that right there is a big fat duh.
Yeah Ivy, you're going to have to back away and take a seat. Let the big boys show you how it's done.
