Linda: How are things?
Mary: Well, at the moment, trying to get shoes for Sheldon, but they only have these, not the ones he likes.
Linda: Ah. You know, I think that brand is the same kind Einstein wore.
Sheldon: Well, I've never seen a picture of his feet. And you're a grown-up, so you wouldn't lie to me. I guess I have no choice but to believe you. All right, I'll try them.
Mary: Great! [mouths to Linda] Thank you.

Mary: You look great, by the way.
Linda: Oh, thanks. I started smoking again.

Mary: You look nice. Going out to dinner with your husband?
Linda: Ugh, no. Girlfriends.

Mary: Aw, they're so sweet.
Linda: Yeah, life'll suck that right out of them soon enough.
