Leonard: Oh, my God, you look amazing.
Raj: I find you guilty of murder, because you are killing it.
Howard: (imitating Sheldon) Well, technically, the Supreme Court wouldn't determine a defendant's guilt or innocence in a criminal matter. They could only reverse or revamp a jury's conviction based on a constitutional or statutory issue.

Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.

Bernadette: Maybe we should get one of those machines to help her up the stairs.
Howard: You mean a forklift?

Sheldon: Sheldon Cooper does not cry.
Howard: That's true, you'd rust.

Sheldon: Amy, do you think I'm always correcting other people?
Amy: No, not all the time. I mean, just last week, Penny ended a sentence with a preposition. You didn't even mention it.
Sheldon: True. I just waited until I got home and screamed into a pillow.

Amy: Hey, why aren't you in your costume?
Sheldon: I just didn't feel like it.
Amy: You get that I'm wearing a corset because of you, not because I'm tired of breathing?

Howard: You're sitting in my spot.
Sheldon: You don't have a spot. What is wrong with you today?
Raj: Maybe he's cranky because he's off his bathroom schedule.
