The phrase τοὺς εὐρυπρώκτους is a notorious crux at Clouds 960. The adjective εὐρυπρώκτους (wide-hipped) is unique to this passage in Aristophanes, though it alludes to a known comic stereotype of the 'broad-hipped' Socratics or philosophers, contrasting with the 'thin-hipped' (συνωπώκτους) of the preceding line in some manuscripts. The textual tradition is divided: some mss. read εὐρυπρώκτους, others εὐρυπρωκτίους or even εὐρυπρωκτίοις, and the scholia suggest a possible corruption from εὐρυπρωκτίους (wide-hipped ones) to a form that might have been misread or emended. The demonstrative τοῦτονὶ (this one here) refers to the specific figure being mocked, likely Strepsiades or a generic philosopher, but the exact referent is debated due to the surrounding context of the trial scene. The phrase is syntactically anomalous as a direct address or exclamation without a clear verb, suggesting a dramatic interruption or a fragmentary delivery.
