Leonard: You know, I do have a way to get him out of our hair. I've been holding onto this for a few years, but maybe now's the time.
Howard: We can just lock the door; you don't have to kill him.
Leonard: You can't kill him; he'll just respawn at the last save point.

Bernadette: What's so funny?
Howard: Raj is looking for a cheap place to live, and I wrote "India."
Bernadette: Don't post that; be supportive.
Howard: Maybe you should be supportive of my hilarious jokes.

Bernadette: Apple slices? What kind of lunatic goes to McDonald's and gets fruit?

Bernadette: Well, my boss said he hadn't decided yet, so I gently reminded him that he's an old rich white guy, and I'm a sweet little pregnant lady who's not afraid to cry in front of a jury.

Amy: He's been in there a long time. Should I go talk to him?
Mary Cooper: He's upset with me. I should be the one who talks to him. (stays seated and works on her knitting)
Amy: Are you going to?
Mary Cooper: Oh, heck no.

Penny: Do they know why the pipes burst?
Amy: They didn't say.
Leonard: Buildings that have a combination of copper and galvanized steel are susceptible to pinholes and corrosion caused by the mobility of ions in the water. Can't have your head shoved in a toilet as much as I did and not pick up a few things about plumbing.

Howard: The kid with the two shirts screwed us again.

Raj: What's the worst that could come of this meeting?
Howard: I don't know. They take the invention away, and I get nothing?
Raj: Okay, that's not so bad. You know what happened to the scientists that worked on the Manhattan Project? The government forced them to move to the desert. They had to live in secret, and when Oppenheimer objected to what they made him do, they destroyed his reputation.
Howard: What's the point of that story?
Raj: I just read a book about Oppenheimer, seemed like a chance to show off.

Sheldon: Stuart, wait. I do know what it feels like to be left out.
Bert: I know how it feels, too.
Sheldon: All right, this is about me and him; you're not part of it.

Leonard: I would pull this car over and kick you out, but if Penny dumps me, you're all I got.

Raj: Maybe there are other things we have in common. Come dinner-time, do you enjoy eating food?

Penny: Come on, looks don't matter to Sheldon. ... Because he only has eyes for you!
Amy: Nice try.
Penny: Thanks, I was scrambling.

Penny: The new neighbors are weird.

Penny: Well, it's like that science thing. For every action, you have a gigantic and annoying reaction.
Leonard: Just when I thought you couldn't get any hotter.

Sheldon: You know, I just learned Amy went to a theme park without me, but I'm not going to ruin her birthday. I'll wait, and ruin 24 individual hours sprinkled throughout the year.
