Frasier: [on the phone] Oh, yes, Joaquim can only eat certain foods. Well, yes I'd be glad to accommodate them. Let's see, all right. Rice, beans, jerked beef. Any particular reason? I see. Interesting. Okay. Bye. [hangs up]
Niles: Why is Joaquim on such a strict diet?
Frasier: Because the Joaquim they're bringing to dinner is their foster child. From a tiny village on the Pampas. He speaks no English and he gets nauseated when he eats American food.
Niles: So, he's not the conductor of the Buenos Aires Philharmonic?
Frasier: Oh, you are so that other one!
