Amy: (Storming into the apartment) Sheldon Cooper, I've got a bone to pick with you, and I'm about to do it in front of all your friends.
Penny: Yeah, you pick that bone. You pick that bone clean!
Amy: I'm gonna publicly shame you, and then sit back as societal pressure compels you to modify your behavior.
Penny: Ooh, burn!
Amy: And if you don't start treating me better, I'm leaving you for a miniature horse breeder named Armin.
Sheldon: Armin who?
Amy: Armin ... damn it.

Penny: Sheldon, she wanted to show you off to her family, and you stood her up, okay? Look at this adorable, smushy face. Smush, smush, smush, smush.
Amy: You're hurting me.
Penny: No, Sheldon hurt you.
Amy: Before; now it's you.
Penny: Oh.

Sheldon: I think I understand. You're the one person who can say Sheldon Cooper is your boyfriend, but that rings hollow if you can't lord him over others in the flesh. I forget what I bring to the party and what I take away when I leave. Please accept these valuable Cooper Coupons as restitution.
Penny: Sheldon, she doesn't want your stupid…
Amy: Ooh, Science Center. Redeeming. Let's go.
Sheldon: Well played, Amy Farrah Fowler. Let me get my coat. (Whip sound) Oh, grow up, Leonard.

Penny: And that's how a girl makes a scene. I'm sorry, sweetie. You're right. You deserve your weekend. Come on, Amy, let's go.
Amy: What about the Science Center?
Penny: I'll let you hold my hair while I throw up.
