House: (about autistic child, Adam) Why would you feel sorry for someone who gets to opt out of the inane courteous formalities which are utterly meaningless, insincere, and therefore degrading. This kid doesn't have to pretend to be interested in your back pain, or your excretions, or your grandma's itchy place. Can you imagine how liberating it would be to live a life free of all the mind-numbing social niceties? I don't pity this kid. I envy him.
The Worm: 'Allo.
Sarah: Did you say... hello?
The Worm: No, I said "'allo," but that's close enough.
Sarah: Oh... you're a worm, aren't you?
The Worm: Yeah, that's right.
Sarah: You don't by any chance know the way through this labyrinth, do you?
The Worm: Who, me? No, I'm just a worm. Say, come inside, and meet the missus.
