Howard: Hey, uh, so we've been talking, and if you need a place to stay, we'd be happy to fix up the garage for you.
Raj: That would be amazing! I was literally just looking at my moving boxes, trying to pick one to live in.
Howard: I know it's not ideal, but you'd have plenty of space for your furniture, and there's this cool button that makes an entire wall go up and down.

Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.

Howard: So you can never take it (the sweater) off?
Leonard: No.
Raj: Not even to sleep?
Leonard: No.
Howard: So you're just an idiot?
Leonard: It's called proving a point.
Howard: Is the point you're an idiot?

Bernadette: Maybe we should get one of those machines to help her up the stairs.
Howard: You mean a fork lift?

Sheldon: Well, I think it's very nice that you're helping out our friend.
Leonard: I think it's nice that you're taking whatever medication Amy's clearly giving you.

Amy: This isn't about me and Sheldon. This is about Rajesh moving in with Leonard and Penny.
Beverly Hofstadter: Interesting. They've found a need to take yet another roommate. Seems they're avoiding some harsh realities themselves.
Sheldon: I had no idea all our relationships were such a disaster. Boy, you're good.
Beverly Hofstadter: That is the word on the street, dear.

Raj: Maybe moving in was a bad idea. I haven't been here one day, I'm already causing problems.
Penny: You didn't do anything. It's Sheldon.
Leonard: "You didn't do anything.It's Sheldon." That'd make a nice needlepoint pillow.
