Lily: What are you gonna do with Marshpillow?
Robin: Hold his arms back while you beat the goose down out of this bastard. Because that's what best friends do.
Lily: Thanks. It's not gonna help.
Robin: Try it. One punch.
Lily: Ooh. That felt good.
Robin: Mm-hm. Yeah, that's it, sweetheart. Head, body, head. Head, body, head.
