Raj: (Outside, in a sing-song voice) Hello! Howard and Bernadette kicked me out because I told them they're having a girl! Oopsy, I did it again.
Penny: Maybe if we're quiet, he'll go away.
Raj: (sing-songy) You're gonna have to be quieter than that.

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Doesn't anyone have a rod of resurrection? Because if you've got one, I need it bad. Get in here with your rod and give it to me.
Stuart: Okay, you need to say these things in your head before you say them out loud.

Raj: Okay, here we go. [to Leonard & Penny] Say cheese. [to Sheldon & Amy] Say cheese. [to Howard & Bernadette] Say cousin.

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?
