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.

Sheldon: All right, this is another one of my favorite places, the comic book store. Feel free to look around.
Stuart: Vintage comics in back, vintage candy right here.

Howard: What are you guys up to?
Sheldon: Oh, father-in-law, son-in-law bonding. It's going great. Look at what he bought me at the train store. (blows whistle) Yeah, it sounded louder in the car.

Mr. Fowler: Oh, how did you do that?
Howard: Sorry, a magician never shares his secrets.
Mr. Fowler: I'll give you a hundred bucks.
Howard: Sold!
Mr. Fowler: Okay. Hey. Where's my wallet?
Howard: Voilà!

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.

Raj: Oh, my God, oh, my God, she just texted. She's on her way up!
Penny: Raj, calm down. You got this.
Raj: Yes. Thank you, thank you. I got this.
Penny: Just remember, the most important thing is to have fun.
Raj: Stop putting so much pressure on me!

Anu: Hi. [Raj gestures as he's unable to speak] Everything okay? Why are you acting so weird? Raj? [Raj walks into the bathroom with a bottle of champagne] What's going on?
Raj: [champagne cork pops] Be right out! You look beautiful!

Raj: Hey, Leonard, can you pause the game for a second?
Leonard: Uh, hang on. I'm about to beat Howard. [after Howard pauses the game] What? Hey!
Howard: He's our friend. What's up, pal?

Raj: I don't know how else to say this, but, um, Anu and I are going to have sex tonight.
Howard: Yeah!
Leonard: Do you know how creepy that sounds?
Howard: Yeah!

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.

Bernadette: I'll tell you one thing. Lock the door.

Penny: Yeah, Raj, you're gonna be fine. Just break out some of your Kama Sutra moves.
Raj: I don't really know any of that stuff. I just pretend I do to impress women. And by the way, Anu is Indian, she's gonna know there's no sexual position called a "screeching lotus."
Bernadette: Screeching lotus?
Raj: Sometimes I get leg cramps. It's my cover story.

Penny: Look, she's probably nervous, too.
Bernadette: Yeah, what if you're great and she's bad?
Raj: How can she be bad?
Penny: Raj, women can be bad at sex, too.
Raj: (laughs) No, that's silly.

Amy: You're up early.
Sheldon: Huh? Yes. I wanted to get a jump on planning a day of fun for you.
Amy: Oh, that's sweet. What are we doing?
Sheldon: Oh, no. Just you. I have other plans. Now, would you prefer to see The Grinch in 2-D or 3-D?
Amy: I don't want to see it at all.
Sheldon: Well, let's go 2-D. No sense in spending extra money.
