Sheldon: After last night, I got to thinking that I should have a better relationship with your family.
Amy: I think the one you have with them is perfect.
Sheldon: I hardly have one at all.
Amy: Which is perfect.

Sheldon: Oh, Amy, they're important to you, and you're important to me. Therefore, according to the transitive property, they're important to me. It's the same reason I'm interested in your big, flat feet.

Amy: Well, you know that my mom can be well, difficult to get along with.
Sheldon: Which is why I'm starting with your dad and working my way up.
Amy: All right. I'm just worried you might have a rather unpleasant day.
Sheldon: Yeah, back at ya. I watched the trailer for The Grinch, it looks terrible.

Mr. Fowler: Hi, Sheldon.
Sheldon: Oh, good. You're right on time.
Amy: Hi, Daddy.
Mr. Fowler: Hey, pumpkin.
Sheldon: Pumpkin? I've been calling her spaghetti squash. It's amazing that one woman can be different vegetables to different men.

Leonard: How you feeling about it?
Raj: Uh, to be honest, I'm pretty anxious. I mean, this is the woman I'm marrying. What if it's no good? Do we break up? Do we sign on for a lifetime of mediocre sex?
Leonard: Just don't put so much pressure on it. It's always a little awkward in the beginning. I remember the first time I slept with Penny.
Raj: It was bad?
Leonard: Oh, it was awesome! I will replay it in my head until the day I die.

Howard: Well, if it helps, I was really nervous my first time with Bernie. Mostly because I was worried my mom would walk in.
Leonard: Did she?
Howard: Yea-- Yeah.

Sheldon: It's called Lethal Weapon, but isn't that redundant? Aren't weapons, by their very nature, lethal?
Mr. Fowler: I suppose you're right.
Sheldon: Yeah, and don't even get me started on Unsolved Mysteries.
Mr. Fowler: I didn't get you started on Lethal Weapon.

Penny: Raj, it's gonna be okay. Look, sex isn't the most important thing in a relationship.
My first time with Leonard was nothing to write home about.
Raj: Really?
Penny: Yeah, but, you know, over time it got better.
Raj: So practice makes perfect?
Penny: Well, practice makes better.

Anu: Sorry, I had to use the facilities. With a bottle of champagne?
Raj: Mm, I like to celebrate the little things in life. You need to go? There's still some left.
Anu: Raj, what is going on?
Raj: No, no, it's not what's going on, it's what's comin' off.
Anu: Stop it. You're acting weird, and it's freaking me out.
Raj: Why? Because I couldn't talk and ran in the bathroom to slug back a bottle of champagne when I pretended to pee?

Sheldon: Excuse me, Turnip, we need to get going.
Mr. Fowler: But-but Howard was gonna show me some close-up magic.
Sheldon: Well, if you want to see real magic, I'll take you to Union Station, home to trains, subways and buses that, every half hour - voilà - drive to the airport.

Raj: Okay, you wanted the truth, here it is.
Anu: You have a drinking problem.
Raj: No. I, uh, I have a talking problem, and a drinking solution.

Anu: If it makes you feel any better, I've got things I'm embarrassed about, too.
Raj: Really? Will you tell me one?
Anu: Okay. Um, ugh. I hate telling people this. I don't like music.
Raj: What kind of music?
Anu: Just all of it. It sort of seems like a waste of time.
Raj: Even Beyonce?
Anu: See, this is why I don't tell people.
Raj: No. Um, it's fine. It's just, have you heard "Single Ladies"?
Anu: Yeah, and I don't get it. I mean, the lyrics are "Oh, oh, oh, oh, oh, oh."
Raj: You have to sing it in the voice of a goddess. Like: Oh, wa-ah, oh Wa-ah, oh Oh, oh, oh Wa-ah, oh. (laughs)
Anu: My point is, we both have our little eccentricities.
Raj: Little eccentricities? One is a deep-seated psychological disturbance, and the other can be solved by half a glass of chardonnay.

Sheldon: So, your turn. Uh, other than Amy, have you every had anything removed from your body?
Mrs. Fowler: I am not going to answer that.
Sheldon: Smart. Save something for our next get-together.

Sheldon: Oh, we should commemorate this one with a selfie. Oh, look at us, two peas in a pod. Oh, speaking of vegetables, how about I start calling you Old Lady Green Beans?

Penny: So you've been using Sheldon as an excuse to get out of seeing your mother?
Amy: I know. I feel terrible. I love my mom but, you know, sometimes-
Penny: Yeah. We-We've met her.
