Leonard: Should we have invited her for lunch?
Sheldon: (unlocking door to their apartment) No, we're going to start season two of Battlestar Galactica.

Leonard: We already watched the season two DVDs.
Sheldon: Not with commentary.

Leonard: I think we should be good neighbors. Invite her over, make her feel welcome.
Sheldon: We never invited Louis-slash-Louise over.
Leonard: Then that was wrong of us. We need to widen our circle.
Sheldon: I have a very wide circle. I have 212 friends on MySpace.

Leonard: Yes, and you've never met one of them.

Sheldon: That's the beauty of it.

Leonard: I'm going to invite her over. We'll have a nice meal and ... chat.
Sheldon: Chat? We don't chat, at least not offline.

Leonard: Well, it's not difficult. You just listen to what she says and then you say something appropriate in response.
(Leonard knocks on Penny's door.)
Sheldon: To what end?

Leonard: Hi ... again.
Penny: Hi--
Sheldon: Hi--

Leonard: Hi--

Penny: Hi.

Leonard: Anyway, um.... We brought home Indian food? (holds food bag toward Penny's face) And, um.... I know that moving can be stressful, and ... and I find that when I'm undergoing stress, that good food and company can have a comforting effect. Also, curry is a natural laxative and I don't have to tell you that, y'know, a clean.

edit: forgot the laugh track
