Althea: Sweetheart, go home. Come back when the contractions are five minutes apart for an hour.
Raj: I'm sorry. That's ambiguous. Is it five minutes apart starting at the top of the hour, or five minutes apart starting with the first contraction, so essentially, like, 65 minutes?
Althea: I'm just throwing this out there, but home births are very popular these days.

Althea: What is this?
Howard: It's a robot arm.
Althea: Where's the rest of the robot?
Howard: I only built the arm.
Althea: Because that's all you needed, right?

Leonard: Is this the high-IQ sperm bank?
Althea: If you have to ask, maybe you shouldn't be here.

Althea: Fill these out.
Leonard: Thank you. We'll be right back.
Althea: Oh, take your time. I'll just finish my crossword puzzle. Oh wait.

Amy: What is this?
Sheldon: A functional MRI of my brain. I did Sudoku before they took it so I'd be ripped.
Amy: I love it. Thank you.
Sheldon: And it's not just an MRI. The orbitofrontal cortex is lit up because I was thinking of you.

Penny: Howard and Bernadette's kid might be born on your birthday. How cool is that?
Amy: Yeah, but I thought this baby was supposed to ruin their sex life, not mine.

Raj: Don't come to the hospital. We're headed home.
Penny: Oh, that was fast. Did she sneeze the baby out?
