The Swan as Metaphor for Love is also available in Joyland Retro Vol. 1 No. 3.
A swan's foot, like a duck's, is a webbed claw. In traversing swan shit and mud, the claws gunk up and reek. Nobody in the history of the world, save another swan, has licked a swan foot while that foot was still attached to the swan. The feet resemble rabid bats in their sickly color and texture.
Moving north on the swan's undercarriage, one will find an eroded civilization of swan shit and pond scum. This is a banal phrase, "pond scum," one that is easily ignored, but look closer, take a more personal approach. Swans eat grasses, sedges and pond weed, each teeming with murk. The birds will also eat insects, snails and a fresh shrimp if they're near one.
