Leonard: And Amy's your best friend. I'm sure she'll come to her senses and pick you.
Penny: Okay, she's not my best friend. We're not 12. If she wants Bernadette to be her maid of honor, I really don't care.
Leonard: Sounds like you care.
Penny: No, I mean, it-it's just annoying. You know, we talk every day. We see each other all the time. She's always there for me, and basically-- oh, my God, Amy's my best friend.
Leonard: You okay?
Penny: No, my best friend didn't ask me to be her maid of honor. I'm pissed!

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?

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

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.
