Sheldon: I couldn't sleep.
Penny: I told you those Walking Dead pillows were a bad idea.

Penny: How about we toast your new found freedom?
Sheldon: Normally I refrain from alcohol, but since my cerebral cortex is twiddling its proverbial thumbs. Why not soak it in grape juice that's been predigested by a fungus?
Penny: And you wonder why other children beat you with books. Cheers!

Penny: There's not even a bathroom on set. I have to go to the gas station across the street. I mean, I was dressed like half an ape and still not close to the most disgusting person in there.

Penny: You know what, maybe I need a break from all of you. Come on, Sheldon.
Sheldon: Where are we going?
Penny: We're going to have Anything Can Happen Thursdays, you're going to tell me all about your science stuff and I'm going to complain about my movie, and we're going to support each other because that's what friends do.
Sheldon: Okay. Because if I had to pick now, I'd probably go with dark matter-
Penny: Shut. Up.

Penny: Wow, you really struck a nerve. I've never heard him use the M-word before.

Leonard: May the force be with you. Get it?
Penny: Oh no, this face wasn't because I didn't get it.

Raj: Before you go, at least let me pack you some Attack of the Scones for the road.
Penny: Ohh, like Attack of the Clones. ... We are leaving right now!

Penny: He can take care of himself. We went over Stranger Danger and gave him that whistle.

Penny: He'll be okay. You taught him well, Padawan.
Sheldon: Good Lord. Padawan is the student, not the teacher.
Penny: Seriously, let him go.

Penny: So, if you don't mind me asking, do you think you might start dating again?
Dr. Koothrappali: It's much too soon for that. Why, do you know someone?
Penny: No, but if things don't work out with me and Leonard, I'll call you. Wait, how much do you talk about Star Trek?

Penny: It's kinda boring. Although it did get exciting for a minute when Amy inhaled a wool ball.

Penny: There's got to be something fun we can do that the guys will hate.
Leonard: Hang on, why do we have to hate it?
Penny: Three words: Doctor Who convention.

Penny: Have fun.
Sheldon: Oh, I will. Nothing more fun than a paradigm shifting evening of science.
Penny: (To Leonard) And you thought it was soaping me up in the shower.

Penny: Hey, shouldn't you be out with your gang, spray painting equations on the side of buildings?
Leonard: Come on, I'm sorry.

Sheldon: Are you familiar with the Higgs boson?
Penny: Of course, it is - it's been in the news. And it's a very famous boson.
Sheldon: Nice try.
