And one man in his time plays many parts,
His acts being seven ages. At first the infant,
Mewling and puking in the nurse's arms;
And then the whining schoolboy, with his satchel
And shining morning face, creeping like snail
Unwillingly to school. And then the lover,
Sighing like furnace, with a woeful ballad
Made to his mistress' eyebrow. Then a soldier,
Full of strange oaths, and bearded like the pard,
Jealous in honor, sudden and quick in quarrel,
Seeking the bubble reputation
Even in the cannon's mouth. And then the justice,
In fair round belly with good capon lined,
With eyes severe and beard of formal cut,
Full of wise saws and modern instances;
And so he plays his part. The sixth age shifts
Capon : Chicken 
 
 Here, the phrase ‘good capon lined’ can either represent the rewards one reaps later life, or is a euphemism for taking a bribe. 
 At this time a chicken was good food, but a capon is not a mere chicken; a capon is a castrated cockerel. The act of castration requires additional expertise and effort in poultry farming. It is done to improve the taste and texture of the flesh for food. Excellent food was a luxury afforded to the wealthy and powerful. The round belly filled with many and frequent meals of fine food denotes wealth, power, and prestige.
