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?

Stuart: Okay, I'll go. Howard, when I think about you and Bernadette starting this wonderful life together, I can't help but get a little choked up. I mean, look at you. You have everything. Look at me. I'm 37. I sleep in the back of a comic book store, and I have the bone density of an 80-year-old man. To Howard.

Bernadette: Hey, Stuart.
Stuart: *startled* Hey.
Bernadette: Sorry, did I startle you?
Stuart: Yes, but at this point pretty much any customer does.

Penny: You really going to lie on the floor and pretend to be dead all night?
Stuart: What do you think I was going to do at home?

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.

Penny: Wow, it looks really pretty in here.
Stuart: Yeah, turns out half a dozen Menorahs really sets a mood.

Raj: In the last hour 162 people have read our profiles. How many of them have sent us messages?
Stuart: Combined?
Raj: Yes.
Stuart: Zero.

Stuart: Anyone else need anything before I go?
Howard: I'll give you a dollar if you make fun of Raj.
Stuart: That's mean.
Howard: Five.
Stuart: You look like Tigger if Tigger looked like a jackass.
Howard: Uh, if you ever need a reference or anything, just let me know.

Howard: Don't take this the wrong way, but did you do this for the insurance money?
Stuart: No! God, you sound like the police, the fireman, my parents, my therapist and the insurance company.

Stuart: Whoa, whoa. You're not gonna cut open a meteor, are you? Have you not learned anything from comic books? Space viruses? Pod people? I sell nothing but warnings.

Stuart: Would you mind stocking these?
Denise: Actually, I'm not on the clock today. I'm just hanging out with my boyfriend.
Stuart: Ah, cool. Huh. That's me, right?
Denise: Oh, I forgot to tell you, I broke up with you, and now I'm dating that guy.
Stuart: I know you're joking, but my flight-or-flight response doesn't.
Denise: Isn't it fight-or-flight?
Stuart: Not for me.

Howard: What kind of music are you thinking of?
Stuart: I like all kinds of music, but my favorite genre is free.

Leonard: Oh, hey, Stuart. This is Penny. She's looking for some comic books.
Stuart: Oh, really? Blink twice if you're here against your will.

Stuart: I can't believe she's gone. That woman took me in. If it wasn't for her, I would have been homeless.
Amy: One of us would have taken you in.
Stuart: Yeah, I don't recall any offers. But you know what, I'm glad it worked out the way it did, because I got to know this wonderful person.
