[Scott playing with his BB gun]
Stiles: Watch the gun, Cool Hand Luke.
Scott: [stands up] Relax. Guns don’t just go off by accident.
Lydia: Oh really? What about Stiles’s fourth-grade hamster, Snowball?
Stiles: What? No, Snowball didn’t get shot. He went upstate to live with a nice farm family. [catches on] You shot Snowball?!!
Scott: The gun went off by accident!
