Martin: You got something you want to say, son?
Martin: Fine. (signals the waiter)
Frasier: Well, all right, if you insist on dragging it out of me. Something happened this morning, Dad.
Frasier: Well, I was, uh, walking down the hall to retrieve my coffee, and, uh, Ronee was on the phone, and I didn't want to interrupt, so I waited, and I heard her make a... a date with another man.
(Martin sits back, stunned... and takes it badly)
Martin: So you eavesdropped, huh?
Martin: Well, a person's having a private conversation. You stop and listen - that's eavesdropping!
Frasier: Dad, it was completely by accident. I understand why you'd be upset, but please don't shoot the messenger.
Martin: Well, the messenger's got it coming if he's a dirty little eavesdropper! You walk into a private conversation, you make your presence known by some subtle way. You can-can clear your throat- (clears throat) you can make a noise- (hits the table)
Frasier: Dad, please!
Martin: (gets up) You know, just because people call in for your precious pearls of wisdom on the radio, it doesn't give you a free pass to get into everybody's business! Now I know why you're always saying, "I'm listening" - because you always are!
