Bernadette: Hey, Stuart.
Stuart: *startled* Hey.
Bernadette: Sorry, did I startle you?
Stuart: Yes, but at this point pretty much any customer does.

Bernadette: I accidentally destroyed one of Howard's comic books this morning and I was hoping I could replace it.
Stuart: What happened?
Bernadette: Batman got his ass kicked by my curling iron.
Stuart: Don't let the Riddler know that. It's a comic book joke.
*Bernadette stares blankly*
Stuart: Or maybe it's not.

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

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.

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

Howard: You know if you'd rather skip lunch and hang out with your boyfriend, Bert. It's totally okay.
Amy: He's not my boyfriend.
Raj: Are you sure? He's tall, pale and awkward. That sounds like your type.

Amy: (To Raj) Should somebody as lonely as you really be making fun of me?
Raj: Yeah, grow up, Howard! God.

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.

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.

Sheldon: Where's my lemonade?
Penny: I didn't get it.
Sheldon: A fitting swan song to your career as a waitress to forget my order one last time.

Sheldon: When I decided I was going to be a physicist, I didn't take some other job in case it didn't work. Which wasn't easy, because there was a lot of pressure from Ms. Pearson to be chalk monitor that year.

Penny: Thank you, I needed to hear that. Why can't Leonard understand it?
Sheldon: Because he's not like us, Penny. We're dreamers!
Penny: Yeah, I need to start cracking the window when I leave you in the car.

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.

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.

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