Quote from Phil in Ringmaster Keifth
Phil: As I guess you heard, I had no reason to be worried. He didn't even notice when Lorraine was my babysitter. Plus, they're not even that serious. Claire: I felt a ring box in his pocket. Phil: What? No way. Claire: Yep. There's only one thing shaped like that. Phil: No, there isn't. There's a million things Rubik's Cube, sewing kit, souvenir tire keychain from Smokey-Top. I can't think of anything that's not shaped like that.
