Bernadette: You know, you're a successful woman. You should be able to brag about your accomplishments once in a while.
Amy: Well, so should you. I mean, the guys are never shy about bragging.
Bernadette: Tell me about it. Howie texts me every time his dog levels up in Warcraft.

Amy: You know, dealing with cold feet is an important part of being both best man and maid of honor. Maybe we should test for that ability.
Sheldon: You really think you might get cold feet?
Amy: Actually, I was talking about you.
Sheldon: Amy if there's one thing in this world I'm sure of, you are right to be worried.

Amy: You know, this is really fun. I can't believe that people say that planning a wedding is one of the most stressful things in life.
Sheldon: I know. Not a day goes by that I don't marvel how much better we are than other people.

Sheldon: We've assigned all wedding decisions randomly, and each of us makes half of them. You know, from venue to officiant to numbering system for the tables: Roman or Dewey Decimal.
Leonard: Why not hexadecimal?
Sheldon: 'Cause this is our wedding, not a joke.

Amy: I think you'd be great at that. Don't you agree, Bernadette?
Bernadette: Huh? I'm listening. I'm listening. I'm not watching The Crown.

Leonard: No, we don't need to be cheered up. It just turns out that physics is exactly like Lost. Started out great, and turns out just a big old waste of time.

Sheldon: Wait. The premise is that he is dressed differently?
Howard: Yeah.
Sheldon: (laughing) That's true. He is not dressed the same.

Stuart: Obviously, vibranium is the most powerful metal in comics.
Raj: What, more powerful than adamantium?
Sheldon: He's right. Wolverine's claws, Ultron's outer shell. Need I go on?
Howard: You don't need to, but you probably will.

Raj: They asked me what my biggest weakness was, and 45 minutes later, they thanked me for coming.

Penny: Have you ever thought about talking to some kind of therapist about all this?
Raj: Ugh. Maybe. Hey, Leonard, do you think your mom would be available?
Leonard: Yeah, you don't want to do that. Talking to my mom to get more confidence is like talking to a lion to get more alive.

Amy: Would you call yourself a loyal and trustworthy friend?
Raj: Yeah, I like to think so.
Amy: Great. Because I need to tell you something about Howard, but you can't tell him that I told you.
Raj: Nope. Don't want to hear it. Do not like to engage in gossip.
Amy: Okay. I respect your integrity.
Raj: Is it about his special underwear? Because I already know. And that's all I'll say. Fine, it has a charcoal filter in it.

Sheldon: Well if the ushers are so important to you, what if I propose a trade? You may pick that, and I will decide, say, first dance.
Amy: Great. Then the ushers will be my cousins dressed in frontier frock coats.
Sheldon: Oh. And the first dance will be that we won't have one.
Amy: All right. Then our second dance will be the first dance.
Sheldon: Unless we have no dance at all.

Leonard: You know, Penny and I aren't the only ones who've broken up. So did Howard and Bernadette.
Raj: Uh, not to brag, but all my breakups have lasted.

Raj: This baby's got a ten-inch diameter with f/10 ACF optics.
Howard: And tonight Mercury is at its highest elongation.
Sheldon: It makes far-away things seem close, and Mercury is a planet.
Penny: I know Mercury is a planet. But the-the other thing was helpful.

Howard: You and Amy having fun planning your wedding?
Sheldon: We're employing a mathematical approach called decision theory, so, heck, yeah.
Leonard: Heck, yeah? Looks like someone need to put a dollar in the almost-swear jar.
