Leonard: I regret not saying "yes"when you asked me to marry you.
Penny: Well, it just wasn't the right time.
Penny: And this is also not the right time. Do not propose.
Penny: I know that face. That's your propose face.
Leonard: I'm not a crybaby.
Penny: Toy Story 3?
Leonard: They were holding hands in a furnace!
Sheldon: When Darth Vader struck down Obi-Wan, did Luke cry like a baby and go to his funeral?
Penny: No. He blew up the Death Star. Why do I know this?!
Penny: Hey, I don't understand why you're not upset with Amy.
Sheldon: I am. So much so that I'm gonna bring her here for dinner on our next date night.
Sheldon: I don't understand my food. Chinese noodles with Korean barbecue ... in a taco.
Penny: It's fusion.
Sheldon: Well, my mother would lock her car doors if she had to drive through this hodgepodge of ethnicity.
Sheldon: So, we're just randomly choosing a restaurant without researching it online?
Sheldon: Great. You know, this is how Anything Can Happen Thursday turns into It Won't Stop Coming Up Friday.
Leonard: All right. I officially reinstate Anything Can Happen Thursday.
Penny: Great! What do, what do you want to do?
Sheldon: I don't know. What do you want to do?
Penny: I don't know. What do you want to do?
Leonard: I'm starting to remember the problem with Anything Can Happen Thursdays.
I have to go to the gas station across the street. I mean, I was dressed like half an ape and still not even close to the most disgusting person in there.
Penny: So, we're about to shoot this scene in the movie where the killer ape DNA is slowly taking over my body.
Penny: But I realize they're gluing fur everywhere, except my cleavage. So, I asked
the director why and he says, it's important to the story that my boobs be the last things to turn ape.
Leonard: It's sweet that he thinks there's a story.
Penny: Wait. What's wrong with geology?
Sheldon: Let me put this in a way you'll understand, Penny. You remember how you explained to me that the Kardashians aren't real celebrities? Well, geology is the Kardashians of science.
Penny: I gave him a new look. It's cute, huh?
Amy: Yeah, it's cute. That's the problem. I don't need other girls to see him walking around like sex on a stick.
Sheldon: She's right. I'm too hot.
Sheldon: Quick poll: PS4 or Xbox One? Raj.
Raj: Uh, Xbox One.
Howard: Both great.
Bernadette: I like the Wii.
Sheldon: Thanks, Grandma
