Mary Cooper: Thank you for picking me up.
Sheldon: Oh, you're welcome.
Mary Cooper: I was speaking to your young lady.
Amy: My pleasure, Mrs. Cooper.
Mary Cooper: Oh, please call me Mary.
Amy: Okay, Mary.
Sheldon: You know, that doesn't work for me, let's stay with Mrs. Cooper.
Mary Cooper: Sheldon, don't be silly.
Sheldon: Wh-, what? That's what I called you 'til I got to know you better.

Raj: Tonight's the night!
Leonard: Yeah, the wait is finally over.
Penny: I know, then you'll finally stop talking about it.

Howard: Hey, I just got an e-mail from the U.S. Air Force.
Raj: Open it.
Howard: Hmm. "We request a meeting at your earliest convenience regarding your quantum guidance system, provisional patent 62/295118." That's weird.
Raj: Is there a window around here we don't know about?
Howard: I'm sure it's just a coincidence.
Raj: Yeah, of course. What else could it be? (loudly) Boy, do I love America!

Mary Cooper: Well, honey, don't send it back yet. Your sister's married, and I'm not letting your brother give my grandmother's ring to that whore he's dating.

Sheldon: A Texas Special cattle and calf car train set with authentic horn and bell! Thank you, Meemaw!
Meemaw: Oh, you're welcome, Moonpie.
Sheldon: Amy, why don't you look excited? You get to watch me play with this!

Beverly Hofstadter: How dare you invite your father without consulting me.
Leonard: Sorry, but I don't think I need your permission to have my father at my wedding.
Beverly Hofstadter: You do understand our marriage ended because he had an affair.
Leonard: I know, and there's no excuse for that.
Beverly Hofstadter: He claimed I was cold, emasculating, and hadn't shown him any physical affection for years.
Leonard: I was wrong, there's three excuses for that.

Dave: Well, no need to be nervous with me. I'm just a harmless giant from a foreign land.

Leonard: Hey.
Penny: Hi, how was the screening?
Leonard: Oh, Sheldon invoked Rosa Parks to make somebody who cut the line feel bad, but only the white people felt bad.
Penny: Ugh, I should've never bought him that colouring book that explains Black History Month.

Sheldon: Why are you up?
Leonard: How am I supposed to sleep? I've been married less than twenty-four hours and my wife isn't speaking to me.
Sheldon: Perhaps you can think of this in a more positive light. In one day, you've managed to do what it takes many couples decades to achieve.

Sheldon: Excuse me, excuse me, can I please see a show of hands? Who here takes issue with this person cutting the line?
Guy: Told you.
Sheldon: Well, what a sad state of affairs. That you've all been so ground down by life, you don't even notice when someone disrespects you.
Howard: I can't believe we're gonna get beat up, and it's not because of your chair.

Sheldon: Oh, Leonard, great news. We discovered a medium-sized asteroid together.
Leonard: Wow, that's amazing! I'm in a pretty great mood today myself.
Sheldon: Okay. Guess we're gonna talk about you now.
Leonard: Well, we are, because Dr. Gallo made me realize that I'm a worthwhile person and that my feelings matter.
Raj: I learned that for free from a cat poster, but good for you.

Guy: Is this guy for real?
Leonard: Boy, I wish I could say no.

Sheldon: Did you see that? He just cut the line.
Leonard: He's just joining his friends; it's fine.
Sheldon: No, it's not fine. It is a breach of line etiquette.
Howard: We're near the front of the line. We'll get in either way.
Sheldon: What if every person in front of us let someone cut?
Leonard: We'd still get in.
Sheldon: What if each of those people let someone cut?
Leonard: Still get in.
Sheldon: But then each of those people let someone cut?
Leonard: We'd still get in, but first I'd hit you over the head with his stick chair.

Amy: What are you doing here?
Sheldon: I'm here to return your belongings. That's what people who've broken up do.
Amy: And you didn't do your compulsive knocking ritual so I'd open the door?
Sheldon: On the contrary, you no longer get to enjoy my charming eccentricities. We're not friends with benefits.

Claire: Wow. You've been talking about Frozen for an hour?
Howard: You should've seen us after The Good Dinosaur.
Raj: It was a classic western set in the post-Jurassic period, and it changed my life.
