Frasier: Hello, Seattle. This is Dr. Frasier Crane. I have a very special guest with me today, my brother, the eminent psychiatrist, Dr. Niles Crane.
Niles: Hello, Emerald City! What's doin'? What's happenin'?
Frasier: [off air] What the hell do you think you're doing?
Niles: That was my radio persona. Every great radio personality has one.
Frasier: I don't.
Niles: My point exactly.
