A RIDDLE

Stretch the noose, and pull it tight.
Rabbit runs away in fright.
Through the circle, twist around –
take care not to touch the ground.
Should it drop or droop or drag,
you'd be headed for a snag.
Should you wind up at this state,
stumbling, you might lose your gait.
Scarcely Grecian Victory:
Wounded pride and skinned-up knee.
