Day 10 - Best scene ever

I have to admit that this is probably the toughest question. But I think that the scene in 6x11 Down Low when Wilson comes into the restaurant full of people, drops to his knees and asks HOUSE to marry him is not going to get old anytime soon. The past part is the unrelated old lady in the restaurant, who eagerly looks at House and yells "SAY YES!". Bouts of laughter ensue.
