Stuart: I'm excited. I haven't been on a date in a long time.
Howard: Back when I was dating, I'd always wear a new pair of underwear, just in case.
Stuart: It's also been a long time since I bought new underwear. And I probably should, because these are no longer tighty nor whitey.
Bernadette: Okay, I'm out.

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.

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.

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: Do you still want to go out with me?
Denise: Absolutely. Hey, maybe we can go find Nemo together.
Stuart: That's a good one.
Denise: Do your 63 other crayon friends know you're out?
Stuart: Are you just gonna make fun of me all night?
Denise: Probably.
Stuart: Great. So what are we thinking, Chinese?
Denise: Yeah, I'm in the mood for orange chicken.

Amy: Well, Leonard and Penny are our best friends. They know us better than anyone. They said it's the perfect gift. We must be missing something. You don't think it's a marital aid, do you?
Sheldon: Don't be silly. Amy, how is this big glass shaft going to aid our marriage?

Amy: Let's just go to sleep. We'll look at it in the morning with fresh eyes, and maybe it'll come to us.
Sheldon: Fine.
Amy: Or we go tear apart that box and look for a clue.
Sheldon: Staying up past my bedtime and solving mysteries? Who knew married life could be this good?
