Penny: Damn. You have more make-up than I do. You've got better make-up than I do. Yep, I'm borrowing ing this.
Leonard: Hey, hey, hey. This is my comic con make-up. I love you, but there are some things a man doesn't share with his girlfriend.

Penny: Molecules.
Leonard: Okay. come with me.
Penny: Where are we going?
Leonard: To my bedroom. So, I can take everything off but those glasses. And, maybe the boots.

Leonard: I wasn't screwing around with anyone.
Raj: Of course not. She was just sniffing around your goods because she was hunting for truffles.

Leonard: Can I tell you a secret?
Penny: What's that?
Leonard: All these women chasing me, I kinda do feel like Captain Kirk.
Penny: Can I tell you a secret?
Leonard: Sure.
Penny: Keep talking about Captain Kirk and we're all going to stop.
Leonard: Message ... received.

Leonard: It's nice to have a young, attractive woman sniffing around the goods.
Raj: I both hate you and want to be you. It's Ryan Gosling all over again.

Okay, so Wolowitz and Stuart are paralyzed, Santa's dead, and I picked this over sex with my girlfriend.

Leonard: I grew up in a house full of crazy academics. Instead of leaving Santa milk and cookies, we had to leave him a research paper. And, in the morning you could tell he'd been there because that paper would be graded.
Sheldon: No wonder you love Christmas. That sounds amazing.

Penny: Is having a real-life girlfriend that has sex with you getting in the way of your board games.
Leonard: A little bit, yeah.

Penny: You are so butch.
Leonard: Oh, I got a little paper cut.
Penny: Of course you did, your hands are softer than veal.

Sheldon: Is anyone else troubled by the Spider-Man theme song?
Leonard: Why would it trouble you? It's like your third favorite cartoon theme song.
Sheldon: It is, right behind [Sheldon sings "Inspector Gadget" and "Teenage Mutant Ninja Turtles" theme songs]
Sheldon: However, the Spider-Man lyrics posit that Spider-Man's Spider-Man does whatever a spider can.
Howard: Yeah, so?
Sheldon: I can think of many things that Spider-Man can't do that a spider can. One crawl in your ear and die, two legally leave Guatemala without a passport, and three have sex with a spider.

Raj: You got this buddy.
Leonard: Yeah, come on, Howard. Hook that worm.
Raj: You can do it.
Penny: That's great. Cheerleading. Way to man things up.

Sheldon: Leonard, you're my best friend. Why don't you ever take my side.
Leonard: Because I can never understand your side!
