Sheldon: Would you like one, Mrs. Petrescu?
Mrs. Petrescu: Yes. Drink is fun and good friends - Applebee's.
Sheldon: She's learning English from TV.
Mrs. Petrescu: TV, good. Now back to you.

Stuart: I also love how you never use swear words.
Sheldon: You know, it turns out, you can hurt people just as well without 'em.

Sheldon: Stuart, wait. I do know what it feels like to be left out.
Bert: I know how it feels, too.
Sheldon: All right, this is about me and him; you're not part of it.

Sheldon: So until Amy's apartment is fixed, she and I are living here together.
Bert: I lived with my old girlfriend. She was a geologist, too.
Amy: Things didn't work out?
Bert: I came home from work one day and she had taken everything. I'm warning you, hide your good rocks.
