Leonard Hofstadter: Sheldon, you need to apologize to your brother.

Sheldon Cooper: I'm sorry?

Leonard Hofstadter: Yes. Like that, but nicer, and that way.

Sheldon Cooper: I have nothing to apologize for.

George Cooper: I told you this was a bad idea. Sometimes you can't patch a tire. You just got to buy a new one. Actually, that's always the case. Never patch, buy new.
