Raj: Oh, this is amazing. I wish I had a playhouse like this when I was a kid.
Penny: Really? You never had a playhouse?
Raj: No. I mean, my dad did buy the house next door for us to play in.

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Amy, good luck getting these guys excited about a dinner with a theme. I gave up when no one cared about my Tom Hanks-Giving.

Penny: What do you mean new roommate? What happened to Leonard?
Sheldon: The same thing that happened to Homo Erectus. He was replaced by a superior species.
Raj: I'm the new homo in town.

Penny: Where does Sheldon think you are?
Amy: Oh, Sheldon's kind of like a dog, he doesn't really think about me when I'm gone, but he's so happy when I show up.

Sheldon: This reminds me of a traditional Amish barn raising. With everyone pitching in.
Howard: How exactly are you pitching in?
Sheldon: I don't hear anyone else giving facts about traditional Amish barn raising.
Leonard: The rest of us are pitching in with hammers and nails.
Sheldon: Well, facts are my nails, and my voice is the hammer which pounds them through the wood of your skull.
Penny: Well, that is how it feels.

Sheldon: All right, I've kept you in suspense long enough. "Dutch" is a bastardization of the word "Deutsch," meaning German.
Penny: What's German for "annoying"?
Sheldon: Nervig. Why do you ask?
