Sheldon: Oh, I was having a little trouble sleeping and I just thought, uh, seeing as you're up, we could talk.
Penny: Talk about what?
Sheldon: Oh, I don't know. Uh, weather. Uh, fish you could do carpentry with. Why Leonard is such an attractive and desirable boyfriend. Yeah, pick one. Your choice.
Penny: Sheldon.
Sheldon: Did you know that Leonard has a perfect driving record and enjoys the insurance discounts that go along with that? Hubba-hubba.
Penny: Okay, go home, crazy man.
Sheldon: Yeah. Did you know that while Leonard is not considered a tall fellow in our country, in today's North Korea, he's downright average. Hey, talk about a keeper.

Sheldon: My point is, I don't like when things change. So, regardless of your feelings, I would like you to continue dating Leonard. And also, while we're on the subject, you recently changed your shampoo. I'm not comfortable with the new scent. Please stop this madness and go back to green apple.

Amy: (Puts Penny on hold, answers a new call) Hello?
Sheldon: Yeah, just a heads-up: Penny knows that you blabbed about Leonard. She's pretty mad.
Amy: I know. She's yelling at me right now.
Sheldon: All right then, so we're all on the same page.

Raj: Focused Locust.
Stuart: Temple of Yip.
Sheldon: I'm sorry. Wolowitz would never play that card.
Stuart: All right, Lesser Demon Turtle.
Sheldon: Fairy God Monster, I win. Your desperate need for friendship makes you weak.

Sheldon: Do you remember how upset I was when they replaced Edward Norton as the Hulk?
Leonard: Yes, you walked around for a week saying, Sheldon unhappy with casting choice.
Sheldon: But, then Mark Ruffalo was the Hulk in The Avengers, and he was even better.
Leonard: What's your point?
Sheldon: Call me a romantic. I like to think that your Mark Ruffalo is still out there somewhere.

Leonard: I know what the anthropic principle is.
Sheldon: Of course. I just explained it to you. Now, where do you stand on it?
Leonard: Where do you stand on it?
Sheldon: Strongly pro.
Leonard: Then I believe that God created the world in six days and on the seventh he made you to annoy me.

Sheldon: Amy, when I look in your eyes and you're looking back in mine, everything feels not quite normal. Because I feel stronger and weaker at the same time. I feel excited and, at the same time, terrified. The truth is, I don't know what I feel, except I know what kind of man I want to be.
Amy: Sheldon, that was beautiful.
Sheldon: I should hope so, that's from the first Spider-Man movie.
Amy: I'll take it.

Raj: Waiter? A bottle of champagne and three glasses. Oh boy, isn't this romantic?
Sheldon: Oh, I hope that's a rhetorical question, because I have no clue.

Amy: Have I ever told you you're like a sexy praying mantis?
Sheldon: Every time you drink alcohol.

Sheldon: I must admit, I can't help but feel a twinge of envy. He can look out the window and see the majesty of the universe unfolding before his eyes. His dim, uncomprehending eyes. It's like a cat in an airport carrying case.

Sheldon: Raj, where do you stand on the anthropic principle?
Raj: I'm all for it.
Sheldon: Attaboy.
Leonard: Well, hang on. Why do you believe that he knows what it is and I don't?
Sheldon: Oh, Leonard. Let's not take a saw to the branch we're sitting on, shall we?

Raj: Hey, if you guys are free tonight, I heard about a spa where you soak your feet in a pool full of little fish that eat all the dead skin right off them. I don't need to tell you in Los Angeles, sandal season is year round.
Leonard: Actually, I'm hanging out with Penny.
Raj: Oh, okay. Sounds like it's me and you, Sheldon. How about we stick some guppies on those puppies?
Sheldon: As I've stated before on numerous occasions, the only sea creature I would even consider being eaten by is the Kraken. Because the last words I would hear are "Release the Kraken." That never gets old. "Release the Kraken!" Chills.

Sheldon: Besides, I'm having dinner with Amy.
Raj: Oh, okay. I'll just go home and be alone. Which is cool. I eat alone, I sleep alone, I cry alone. So, cool.
Sheldon: Darn. If you weren't busy, I'd ask you to join us.
Raj: Really? I can come? Thanks!
Leonard: Sheldon, are you sure you want to be bringing Raj on your date night with Amy?
Sheldon: Oh, absolutely. I have a contractual obligation to provide Amy with conversation and casual physical contact, but nowhere is it specified that I can't outsource that to an Indian.

Amy: I don't understand. What's he doing here?
Sheldon: I invited him.
Amy: On our date? Sheldon, that's not okay.
Sheldon: Yes, it is. There's a loophole in the Relationship Agreement.
Amy: You found a loophole?

Sheldon: Would you like some aloe vera? 'cause you just got burned.
