Renard

Une queue de renard. A mockery. At one time a common practical joke was to fasten a fox’s tail behind a person against whom a laugh was designed. “Panurge never refrained from attaching a fox’s tail or the ears of a leveret, behind a Master of Arts or Doctor of Divinity, whenever he encountered them.”—Rabelais: Gargantua, ii. 16. (See Reynard.)
