Leonard: No one would talk to me in the halls. They just glared at me. It's like high school all over again.
Penny: Oh, I would totally do high school all over again. But that doesn't help you.

Leonard: I got called in to the administration office.
Penny: Ooh, look at my bad boy getting called to the principal.
Leonard: We don't technically have a principal. There's a standing committee that oversees the budget.
Penny: Ooh, look at my bad boy answering questions nobody asked.

Sheldon: Well, on the bright side, after working together for 15 years, you finally get to hear me say, "You were right."
Leonard: Yeah, you did.
Sheldon: How's it feel?
Leonard: Given I might be unemployed, bittersweet.

Penny: Oh, wow. He's buried with his wife.
Raj: We get it. A lady loved you. Quit bragging.

Howard: This guy knew how to live. He taught himself musical instruments. He studied Portuguese just to give a speech in Brazil.
Raj: The only part of me that's been to Brazil is my bikini line.
Penny: (taking the Romulan ale away from Raj) Okay.

Amy: You know, ever since I was a young girl, I've dreamed of a June wedding, maybe on a cliff overlooking the ocean at sunset.
Sheldon: Sure. Sounds wonderful. Now, if you'll excuse me, I'm going to go clean up. (To himself) Outdoor wedding. I know what I'll be using that cliff for.

Sheldon: Good morning.
Amy: Good morning. I know today is Apple Jacks day, but we're all out.
Sheldon: That's fine. I'll have anything.
Amy: Really?
Sheldon: Yeah. You know whatev.
Amy: "Whatev"? I like this side of you.
Sheldon: You know what I like? Smooth jazz. (plays "Feels So Good")
-Amy wakes up in bed next to Sheldon, who is humming the same tune-

Penny: Well, maybe this is a part of Sheldon's personality he's been repressing. I mean, I think we dream about things we wish we could be in real life.
Amy: Really? What do you dream about?
Penny: Oh. Uh, being the wife of Leonard. Mostly that.
Leonard: I choose to believe you.

Ruchi: Well, moving to a new city was a little scary, but the job seems great. Everyone's really nice.
Bernadette: Oh, they are. Super nice. I mean, only one of them took you out tonight, but it's not a competition.

Raj: Bernie!
Bernadette: Oh, damn.
Stuart: Hey! What are the odds?
Bernadette: Yeah, seren-frickin'-dipity.

Sheldon: You know me, I just go with the flow. Beach, public pool, they both sound awesome. On second thought, beach. I'd like to befriend a seagull.

Leonard: If you want me to object at your wedding, just give me one of these. (taps on his nose)

Raj: I'm just saying, you should bow out.
Stuart: Why should I bow out?
Raj: Uh, because we all know how this is gonna end.
Stuart: That's what my doctor said, too, but I'm still here.

Stuart: Howard, Bernadette was there last night. Did she say anything when she got home?
Howard: Yeah, she said, "Why'd you tell those idiots where I was? Thanks a lot."

Ruchi: It's too bad Stuart couldn't make it. He seemed fun.
Raj: Oh, yeah, he is. I love him dearly, yeah. Not to say that I don't worry about him.
Ruchi: What's to worry about?
Raj: You know what? I'm talking out of school. Speaking of which, he's allowed to live near them now.
