Bernadette: Halley's awake and ready for her party!
Howard: Be right up!
Penny: Ooh, I want to see the birthday girl.
Raj: I'd love to see her.
Bernadette: Walk slow. It takes a while to get this bra back on.

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?

Sheldon: Can I get you anything else?
Amy: No, thanks. I think I'm good.
Sheldon: You sure? There's still plenty of pork fat. Although, if we don't eat it, I suppose we could turn it into soap.
Amy: That might taste better.

Sheldon: Uh-oh.
Amy: What?
Sheldon: I left the food out.
Amy: You afraid it's gonna go good?

Amy: I know we only have coitus on my birthday, but I don't know if I can wait until midnight.
Sheldon: Oh, well, you'll be glad you did. Everyone knows the best foreplay is rigid adherence to a strict schedule.
