I actually thought the party was the worst scene of all. All the characters were completely out of character, House trying to impress people, Foreman being quite obnoxious and having fun etc. Don't know if that was a point that was trying to be made.
I don't remember specifically any favourite scenes, there are several that I liked though.
I get a bit annoyed by how witty he is sometimes though, too unrealistic. The psychological analysis between House and Wilson is very annoying I find also.
