'Pigs (Three Different Ones)' symbolizes the corrupt, authoritarian leaders and moralizing hypocrites who control society, exploiting the 'Dogs' and 'Sheep' for their own gain.

This track takes aim at various figures of authority and influence, portraying them as arrogant and oppressive. The three 'pigs' referenced are allegories for different types of powerful individuals: the first, a general representation of corrupt businessmen or politicians; the second, a specific jab at moral crusaders like Mary Whitehouse ('Whitehouse, you go down to the road / You got to have some kind of creed or go home'); and the third, a more general figure representing ruthless power mongers. Lyrical excerpts like 'You're a powerful man, but you're a goddamn fool' encapsulate the contempt for their hypocrisy and ineptitude. The 'Pigs' are depicted as the ultimate beneficiaries of the societal system, thriving on the labor and obedience of the 'Sheep' and the ruthless ambition of the 'Dogs'. They are above the law, manipulative, and dictate the terms of existence for the other classes. Waters' lyrics convey a deep sense of anger and frustration towards those who wield power without principle, emphasizing their greed, self-importance, and fundamental lack of human decency.
