Howard: Is she single?
Bernadette: I'm not setting her up with Raj.
Howard: What about Stuart?
Bernadette: Are you listening? I want her to think I'm not mean.
Howard: Okay. Well, it's just we have two single friends.
Bernadette: Howie, I just met this woman. Why don't I wait a little and get to know her? Maybe I won't like her, and then I'd be happy to ruin her life with Stuart or Raj.
Howard: That's all I ask.

Howard: I'm sorry I didn't take you to the airport. I just want you to know I'll never forgive myself for being so selfish. And I promise to keep you close for the rest of my life.
Bernadette: Oh, no, that thing's gonna end up in my bedroom.

Bernadette: (Shouting from the bathroom) How many times do I have to tell you to replace the toilet paper when it's empty?
Howard: I'm in the middle of something.
Bernadette: So am I!

Bernadette: Gosh, Amy. I'm sensing a little hostility. Is it maybe because like Sheldon's work, your sex life is also theoretical?

Bernadette: One of the great things about being pregnant is drinking cranberry juice out of a wineglass and watching people freak out.

Penny: Is it possible that you're stressed because you're scared about getting married? I mean, it is a big change, and you're not good with little changes.
Sheldon: Well, that's nonsense. You name one little change I was upset with.
Penny: Uh, when they changed the green Skittle from lime to apple.
Sheldon: That is not the rainbow I grew up tasting.

Sheldon: Why can't there just be one week each month for famous people to die?
Amy: Well, they've already arranged to die in threes. What more do you want from them?
