Amy: That's very nice, but I have a boyfriend.
Bert: That's what they all say. You just don't want to go out with me because I have an off-putting personality.
Amy: No, that's not true. My boyfriend has an off-putting personality, too. Like way worse than you.

Howard: Anybody home?
Amy: Hey. What brings you guys here?
Raj: We were just on our way to lunch and wanted to see if you'd like to join us.
Amy: Why? Because Sheldon's not here this week and you don't think I have any other options -- I'm just kidding! I'll get my purse.

Stuart: I haven't seen this many people in my store since that Korean Church bus crashed through my window.

Leonard: Look, if you want to break up just say it.
Penny: Leonard ...
Leonard: No, I take it back, don't say. Just hate me but stay wiht me. It worked for my parents.

Bert: You know what geologists and Bon Jovi have in common?
Howard: They're both into rock?
Bert: Yeah.

Raj: Do you support this?
Leonard: Of course I do. She's a great actress. I'm proud she's taking this risk.
Amy: That's nice.
Leonard: You bought that!? Great! I gotta call her before I forget how I said it.

Bert: This is awkward. You thought I was going to ask you to go with me to the rock and mineral show.
Amy: Weren't you?
Bert: Yeah.

Jesse: Hey, Stuart. I haven't seen you in forever. Look how grey you've gotten.
Stuart: My hair's exactly the same color as always.
Jesse: No, I was talking about your skin.

Howard: Mineral and rock show? That would be awful even without Bert.

Raj: So we tell him she's a lesbian?
Howard: Of course we tell him she's a lesbian.

Bert: Thanks for coming to the mineral and rock show with me.
Raj: We're sorry Amy didn't want to go.
Howard: Really, really sorry.

Bert: You know what, uh, geologists and Bon Jovi have in common?
Howard: You're both into rock?
Bert: Yeah.

Amy: Hello, Mr. Rat Brain. Not so bitey without the rest of the rat to back us up, are we?

Raj: And does Sheldon know you're dating Sheldon?
Amy: (To Raj) I'm sorry, who are you dating?
Raj: Yeah, knock it off, Howard.

Sheldon: Where is this going? Are you two ever getting married? And if so, where will we all live? Have you thought about that?
Leonard: No.
Sheldon: Penny?
Penny: Okay, wait, what are we doing?
Leonard: For some reason we're planning a future where we both live with Sheldon for ever.
