Howard: If there's a chance someone's gonna see you naked, it's also polite to make sure you're well-groomed down there.
Bernadette: I get it, Howard. I've been busy!

Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.

Howard: So you can never take it (the sweater) off?
Leonard: No.
Raj: Not even to sleep?
Leonard: No.
Howard: So you're just an idiot?
Leonard: It's called proving a point.
Howard: Is the point you're an idiot?

Bernadette: Does your mother call you every day at work to see if you had a healthy lunch?
Howard: My mother calls me every day at work to see if I had a healthy bowel movement.

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?

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.
