Norm claims that he never knew that the bar had a piano. He seemed well aware of it in the first season episode Showdown when Sam's brother dazzled the gang with his piano playing and singing skills.
Cliff: Nice to see Woody in charge, huh? It seems like only yesterday he couldn't find his way around the bar and he got lost in the storeroom.
Norm: That was yesterday.
Frasier: Sam, your whole life has been a string of meaningless albeit enjoyable sexual encounters. Now for the first time you're engaging in a meaningful productive pursuit. It's a common conflict between what we call recreational sex and procreational sex.
Frasier: Oh dirty sex and clean sex.
Frasier: Sam what is it?
Frasier: Is it an accident? A fire? Do you want us to follow you? Sam, look just pull yourself together and tell me what it is.
Sam: I can't.
Frasier: Yes, you can. Just organize your thoughts, form the words, and tell me.
Sam: I can't.
Frasier: Sam, if you want me to help you, you're gonna have to tell me what the problem is.
Sam: I am.
Frasier: Then what is it?
Sam: (yelling) I can't!
Sam: Woody, we're out of here. You're in charge of the bar.
Woody: Why bother, Sam? Whenever you put me in charge nobody every listens to me. I just get laughed at and get drinks poured over my head.
Sam: If anyone does that to you, you just sic Carla on them.
Woody: I'm talkin' about Carla.
Rebecca: Look I don't want it to be that we just do it. I want this to be special. I mean what's going to happen when our child asks us about the night we conceived. What are we going to say?
Sam: How about, "Mind your own business?"
Norm: Sammy, we have a smoking section?
Sam: Yeah over by the piano.
Norm: I gotta turn my head more.
Woody: Of course where's my head?
Carla: Probably in the pumpkin patch wondering when the mix up occurred.
Norm: Cliffie, I hate to interrupt but we're here.
Cliff: Normie, how come you always drop me off six blocks away from my house?
Norm: This time it's a mile. Get out.
Sam: If were gonna have a baby, I'm gonna need my Johnny!
