Abstemius's Fables (Sir Roger L'Estrange)
264. (Abstemius 10) Capons Fat and Lean.
There were a great many Cramm'd Capons together in a Coop, some of 'em very Fair and Fat, and Others again did not thrive upon Feeding. The Fat Ones would be ever and anon making sport with the Lean, and calling them Starvelings; 'till in the End, the Cook was order'd to dress so many Capons for Supper, and to be sure to take the best in the Pen: When it came to that once, they that had most Flesh upon their Backs, wish'd they had had less, and 'twould have been better for 'em.
Prosperity makes People Proud, Fat, and Wanton; but when a Day of Reckoning comes, They are the First still that go to Pot.
