Quote from Ted in The Rehearsal Dinner
Lily: Setting aside the fact that I've kept your whole "moving to Chicago" thing a secret, aren't you supposed to be dressed like Liberace right now?
Ted: Okay, first of all, if I showed up in costume, it would steal from the surprise and spectacle of my grand entrance. And second of all, I'm not doing that.
Lily: Why not?
Ted: Because dressing like Liberace is easy, but...
[flashback to Ted taking a piano lesson dressed as Liberace:]
Ted: Uh, yes, 4/4, e-sharp... Major... Okay. Let's make something beautiful, shall we? [inhales deeply] I think that's
