Jesse: You're back.
Bernadette: *Angry voice* Yes, I am. There's a few more things I want to say to you. Stuart's store is just fine. And he's a much nicer person than you are. And if you still have that comic I'd like to buy it right now.
Jesse: No problem. Want a latte while you wait?
Bernadette: No, I don't want a latte. I want a cappuccino and a blueberry scone.
Jesse: I only have chocolate chip.
Bernadette: Well that sounds even better!

Sheldon: I've changed. Like the frog who's put in a pot of water that's heated so gradually, he doesn't realize he's boiling to death.
Penny: Or you're the frog who's been kissed by the princess and turned into a prince.
Leonard: Or you're just a tall, annoying frog.

Bernadette: I'm glad I got that mocha. And you know what else I'm glad about? I bought you a brownie and I ate it in the car!

Sheldon: The conductor said if I come back to the engine room, he'd show me how to take the train through a crossing.
Amy: Okay. Have fun.
Sheldon: Do you want to come with me?
Amy: Really? I do!

Penny: I just got a part on a TV show.
Amy: Congratulations!
Leonard: That's great. Guys ...
The guys: Yeah ...
Amy: What's the show?
Penny: NC - I I? or, you know, NC - S T D. I don't know. It's the one with all the letters.

Raj: Sheldon, I think you might find the support you're looking for if you realize relationships are a give and take. She can only be there for you as much as you are for her.
Amy: Thank you, Rajesh.
Raj: And Amy, you need to be patient with Sheldon and stop pressuring him into accepting intimacy on your terms.
Amy: You should probably go.

Sheldon: They called it the greatest thing since the Communist party. Although I'm pretty sure the Communist party made them say that. I like China. See, they know how to keep people in line.

Sheldon: How do I make them stop loving me?
Leonard: You could invite them to live with us.

Bernadette: Sorry, I'm late. The leaf blower broke so I had to hand dry my mother-in-law.

Howard: I've never done this before, it's kinda fun.
Raj: Yeah, if your mom could see her little Bar Mitzvah boy, she'd have a heart attack.
Bernadette: Good idea. I'll take a picture.

Sheldon: My brain is better than everybody's!

Leonard: People get things they don't deserve all the time. Like me with you.

Howard: So I'm almost done writing the song for Bernadette. Are you cool playing the cello?
Leonard: If by cool you mean willing to, yes. If by cool you mean cool, clearly you've never seen me play the cello.

Sheldon: What's that animal doing in our apartment?
Leonard: She's in her crate, she can't get out.
Sheldon: I have two words for you: Jurassic Park.

Bernadette: I got into science because I was always the smallest kid in the school. I thought if I became a scientist I could invent a formula that made me taller.
Amy: That's cute.
Bernadette: I thought it was working for a while, but then I found out my brother was just lowering the pencil marks on the door frame.
