Raj: I don't believe in tempting fate. Same reason I wouldn't use a ouiji board or pick a fight with an Asian guy. Probably doesn't know karate, but why risk it?

Raj: Amy, good luck getting these guys excited about a dinner with a theme. I gave up when no one cared about my Tom Hanks-Giving.

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.

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: You better find my husband's mother, 'cause one way or another we're walking out of this airport with a dead woman.

Penny: Do you want to stop? I know you have trouble with eye contact.
Sheldon: Well, you have a brown fleck in your right iris that looks like a Formula 1 race car, so I'm just concentrating on that. Plus it's easier around people I'm comfortable with.
Penny: Oh, sweetie, I'm comfortable around you, too.
Sheldon: Of course you are. I'm warm and soothing. I'm like a human bowl of tomato soup.
