Bailey: [walks in] Hello. [starts singing]
Derek: What song is that? I know that song.
Bailey: Oh, just a little song… stuck in my head, you know how it is. You both, have a great day. [walks out]
Derek: Bailey in a good mood!
Mark: She is. Really good.
Derek: Teddy was right for you, appropiate.
Mark: Appropiate is boring.
Derek: For some appropiate isn’t a problem.
Ben: [walks in] Good morning. [starts singing the same song as Bailey] Gentlemen. [walks out]
Mark: Go Bailey!
