Penny: Hey, what you doing?
Leonard: Oh. Sheldon gave me a brain teaser. It's kind of fun. It's about a group of people at dinner, and you have to figure out where they can sit without fighting.
Penny: Oh, yeah, is this the one where Mr. Green can't sit next to anyone eating meat, and Uncle Light Blue won't sit next to any of the darker colors?

Leonard: What am I supposed to do?
Penny: Err, keep your mouth off other women.

Penny: At one point, they had me figure out how to get a banana out of a puzzle box.
Leonard: Wait, Sheldon gave me a banana in a box. He was testing me, too.
Penny: Unbelievable.
Leonard: And how could a chimp even solve that? That was impossible.
Penny: Really? You couldn't get it out?

Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

Penny: Look, I know this is your wedding, and you can do whatever you want, but if you think anyone but me is gonna be your maid of honor, then you're an idiot because you are my best friend.
Howard: Too late, Bernade-
Amy: (pushes Howard out of the way, rushes to hug Penny) Bestie!

Sheldon: Did Bernadette even try to send us a sewing kit?
Amy: She did. Amazon, standard shipping, not even Prime.
Sheldon: (gasps) We could've done that ourselves.
Amy: (chuckles) That's what she said.

Penny: What did you need the kit for?
Amy: Oh, um Sh-Sheldon was squatting down to pick up a fork and he ripped his pants.
Penny: Oh, someone's gonna be sore tomorrow.
