Big Bang Theory Quote
Leonard: (after Raj shows Amy's new look, and he detested it and stormed out, Leonard follows him) Sheldon, that was really rude.
Sheldon: Well, I'm sorry. Amy is the one constant I can count on, and now she's changing.
Leonard: It's just a haircut and some clothes.
Sheldon: No, it's the last straw! I can't take anymore!
Penny: (the elevator bell dings and the doors open) Can you believe it? They finally fixed the elevator.
