Spartacus (1960)
Marcus Licinius Crassus: Do you eat oysters?
Antoninus: When I have them, master.
Marcus Licinius Crassus: Do you eat snails?
Antoninus: No, master.
Marcus Licinius Crassus: Do you consider the eating of oysters to be moral and the eating of snails to be immoral?
Antoninus: No, master.
Marcus Licinius Crassus: Of course not. It is all a matter of taste, isn't it?
Antoninus: Yes, master.
Marcus Licinius Crassus: And taste is not the same as appetite, and therefore not a question of morals.
Antoninus: It could be argued so, master.
Marcus Licinius Crassus: My robe, Antoninus. My taste includes both snails and oysters.
