I just watched the episode. Can some explain that scene to me? I was not clear what was happening, what they were asking of him, etc. And I did not understand why House was dancing around all happy. I was very confused and ran it back a few times but I did not understand it.

They discussed earlier in the episode how people with the mirror syndrome pick the most dominant person in the room to mirror. Everybody wanted to find out who wore the pants, so to speak, in the House/Cuddy relationship.
