Oh, that's /brilliant/... Hugh and RSL work so well together in real life as well as in House, when Hugh was talking about the goldfish and the hamster...
Oh, and also, a while back, I started this thread on LJ -
http://community.livejournal.com/house_wilson/1818528.html - which has everything House/Wilson-y that House, Wilson, Hugh or RSL have ever said. Ever. Go on, read it, and contribute. There's probably quite a lot I've missed because I live in England and therefore haven't seen Season Four (with the exception of That Scene.)
