Howard: Doesn't she have her own place? Why don't you guys hang out there?
Stuart: Oh, she has a roommate, and he's kind of creepy. A-And that's coming from me.

Stuart: Oh, Sheldon, I'm afraid you couldn't be more wrong.
Sheldon: More wrong? Wrong is an absolute state and not subject to gradation.
Stuart: Of course it is. It's a little wrong to say a tomato is a vegetable, it's very wrong to say it's a suspension bridge.

Howard: Hang on, I know a place where you could you stay and earn some money at the same time.
Stuart: Great!
Howard: I just have to warn you: it will involve humiliation, degradation and verbal abuse.
Stuart: So, what's the catch?

Bernadette: Why are they staring?
Amy: Who cares? Just soak it in. Hello, boys.
Stuart: Oh, hey. (To the other customers) Could you please stop staring? They're just girls. It's nothing you haven't seen in movies or in drawings.
Penny: Hey, Stuart.
Stuart: What brings you guys here?
Bernadette: We were looking for a recommendation about comic books.
Stuart: Oh, well, I recommend you don't open a store and sell them.
Penny: No, we were just wondering why the guys like this stuff so much, so we thought wed give it a try.
Stuart: Oh, okay. What do you think you might be into? Superhero, fantasy, graphic novels, manga? (To the customers) I swear I will turn a hose on you.

Bernadette: When does Anu come back from London?
Raj: Next week. But it's been good, you know? Really given me a chance to focus on myself.
Howard: How's that going?
Raj: I didn't like what I saw, got in my car, drove over here.

Amy: Are you really not gonna pick up your mother?
Leonard: No. It's fine, she likes to take a cab or a shuttle. That way she can meet people.
Amy: Well, that's kind of nice.
Leonard: Yeah, she always says that a stranger is just a person whose emotional weak point you haven't found yet.
Sheldon: Your mom is the best.

Leonard: How was your flight?
Beverly Hofstadter: There were some parents with a baby. A lot of crying.
Leonard: Well, babies do that.
Beverly Hofstadter: No, it was the parents. It seems they couldn't handle some constructive criticism.
