Leonard: That was fast.
Beverly Hofstadter: Oh, the middle stall was occupied. I'll have to try again later.
Sheldon: That's totally understandable. In bladder voiding, as in real estate, it's location, location, location.

Sheldon: Did you remember to ask for the chicken with broccoli to be diced, not shredded?
Penny: Yes.
Sheldon: Even though the menu description specifies shredded?
Penny: Yes.
Sheldon: Brown rice, not white?
Penny: Yes.
Sheldon: You stop at the Korean grocery and get the good hot mustard?
Penny: Yes.
Sheldon: Did you pick up the low sodium soy sauce from the market?
Penny: Yes.
Sheldon: Good. See how it's done, Leonard?

Raj: (Reading Howard's tweet) I am so lonely and horny, I may open this $20 jar of peanuts and end it all.

Sheldon: Bring out the Red Bull, it's time to rock Mario old school!

Sheldon: You're the milk thief! Leonard said I was crazy but I knew that carton felt lighter.

Penny: Can we go talk in the living room?
Sheldon: I'm not wearing pajama bottoms.
Penny: Why not?
Sheldon: I spilled grape juice.
Penny: Well, wear different pajamas.
Sheldon: I can't wear different pajamas. These are my Monday pajamas.

Sheldon: Hey, Stuart, have you read the new Flash?
Stuart: No.
Sheldon: Well I have and it will knock your socks off. Good luck getting them back on.

Sheldon: Just when I think I've gotten the hang of sarcasm.

Sheldon: Penny, I'm a physicist. I have a working knowledge of the entire universe and everything it contains.
Penny: Who's Radiohead?
Sheldon: I have a working knowledge of the important things in the universe.

Howard: Here's an approximation of the spare parts available on the Space Station. We gotta find a way, using nothing but this, to reinforce this so the waste material avoids the spinning turbine.
Raj: You mean so it doesn't hit the fan?

Leonard: Come on, there's four of us and one of him.
Sheldon: Which means his triumph will be even larger. Minstrels will write songs about him.

Penny: David is not smarter than you, because a smart man would take the naked pictures of his wife off his phone before trying to take naked pictures of his girlfriend!
Leonard: He tried to take nude photos of you?
Penny: That's what you took from that?! The guy is married!
Leonard: Oh, that's terrible.
Penny: And you, if you're so fine with how the way things are between us then why are you so jealous?
Leonard: The important thing is he's married and that's terrible.
Penny: Nice save, genius.

Raj: I hate trains.
Sheldon: Oh, don't be silly. You love trains.

Sheldon: We're gonna have to stop at Pottery Barn on our way to work. I bought these Star Wars sheets, but they turned out to be much too stimulating to be compatible with a good night's sleep. I don't like the way Darth Vader stares at me.

Leonard: We had a vote. Three of us voted for airplane. Sheldon voted for train, so we're taking the train.
Sheldon: Don't say it like that, Leonard. Say it like, "We're taking the train!"
