Niles: How about Desmond?
Daphne: Desmond Crane. "Desmond Crane, you are hereby sentenced to..." No, I don't like it. What about Jack?
Niles: 'fraid not. The first name ends with the same sound that begins the last name. So you either end up running them together, "Jack-rane", or you face the dreaded glottal stop, "Jack Crane", "Jack Crane". It's unpleasant for the throat.
Daphne: This conversation's unpleasant for the throat.
