When Hugh said the line something like "Because I can't come up with any more amusing things to say", he totally slipped up at the end and started laughing. I wonder why they used that take. A little quirky smile would be like House, but that was a little too much of a laugh. Were I the director, I would have reshot that scene.

y'know, I didn't even think about that until you mentioned it. i actually brought that up to my dad, who noticed it too. i feel like that whole line was ad-libbed and the directors were like, "hey, that was pretty funny... let's keep that!" and they kept that scene the exact way it was shot. i kinda wanna see that part of the show again...
