Niles: Oh, uh, Alistair. Congratulations, it was a stunning production.
Alistair: Well, thank you, Niles.
Daphne: It must be awfully hard work putting on an opera.
Alistair: It is utterly draining. In fact, when I'm in rehearsals, I devote every ounce of strength to it. No exercising, no jogging, I even abstain from sex. Well, you can ask Frasier here. My poor, dear, patient Frasier.
