(Jerome Belasco, a "godfather" type, having done Niles a favor, has shown up unexpectedly at Frasier's)
Niles: (to Frasier) Do you think that's why he's here - to collect?
Frasier: No Niles. He's probably hosting a luau; he came by to borrow our poi ramekins.
Poi ramekins are small dishes in which Poi is served. Poi is a Polynesian staple food made from the kalo (or taro) plant.
