Amy: So, I guess you're not gonna help them?
Sheldon: Oh, I'm gonna help them. Help them get on the right side of Johnny Law.
Amy: Oh, you can't turn them in. The city's gonna make them rip out all the work they've done and do it over. It would be the end of your friendship.
Sheldon: What choice do I have? These are the rules.
Amy: Sheldon, I am begging you. Please, don't do this.
Sheldon: You know who doesn't get permits for their decks? Animals.
Amy: Animals don't have decks.
Sheldon: Oh, really? I have one word for you: beavers.
