Sheldon: Excuse me, Penny, but-
Leonard: Don't tell her.
Sheldon: We're playing Klingon Boggle.
Leonard: Aww!
Howard: What do you mean "Aww?" Like she didn't know we were nerds?

Wolowitz: Winnie-the-Pooh is out of the honey tree.

Wolowitz: Puppies, how do you stand on puppies?
Bernadette: A puppy once bit my face!
Wolowitz: Of course it did.

Beverly Hofstadter: It might explain why the two of you have created an ersatz homosexual marriage to satisfy your need for intimacy.
Howard: Say what?

Priya: Indian parents are very protective of their children.
Howard: Right. Whereas Jewish mothers take a casual la-di-da approach to their sons.

Howard: What's the matter, you chicken?
Sheldon: I've always found that an inappropriate slur. Chickens are not by nature at all timid. In fact, when I was young, my neighbor's chicken got loose and chased me up the big elm tree in front of our house.
Raj: Chickens can't climb trees.
Sheldon: Thank God.
Howard: Okay, I believe the chicken made you his bitch.

Wolowitz: Raj, there's no place for truth on the Internet.

Howard: Well, she's free to examine my briefs.
Leonard: Howard!
Howard: I know! I'm disgusting. I should be punished. By her. Oh, look I did it again.

Howard: If you don't want to use dating Web sites, what do you suggest?
Sheldon: Off the top of my head? Prospective women weed themselves out in a battle of wits until only one champion remains, she shows up at my door flush with the thrill of victory, and then sits quietly by my side while I watch Daredevil.
Howard: You seriously think women would fight for you?
Sheldon: People compete for jobs and trophies, why not me?
Howard: He's right. He knows a lot of jokes.

Howard: Don't be oversensitive. He's calling you illiterate, not your race.
Raj: Oh, okay. Good.

Howard: Settle this. Those little animated pictures on the Internet, are they called "gifs" or "jifs"?
Leonard: Well, the G stands for "graphics." That's a hard G, so I'd say "gif."
Raj: What? The guy who invented it says it's "jif."
Howard: I'm sorry, do you mean the guy or the juy?

Wolowitz: Well no, you're mistaken. You give speeches all the time. What you can't do is shut up.

Howard: Sheldon knows football? I mean Quidditch, sure, but football?

Howard: We're looking for Sheldon, not Marmaduke.

Sheldon: I don't care for novelty editions of Monopoly. I prefer the classics: regular and Klingon.
Howard: Actually, Indian Monopoly is just like regular. Except the money is in rupees and instead of hotels, you build call centers. And when you pick a chance card, you might die of dysentery. Just FYI, that was racist.
