Which Shakespeare Play Contains The Line, "All The World's A Stage"�?

These words appear in Act II of "As You Like It." They are spoken by Jacques, a melancholy companion of a duke living in exile in the Forest of Arden. Jacques goes on to outline the seven roles that a man plays during his lifetime on the "stage." These are: the infant "mewling and puking in the nurse's arms"
"the whining schoolboy" creeping reluctantly to school
the lover, sighing and writing romantic verses "to his mistress' eyebrow"
the soldier, bearded and swearing, risking his life in search of "the bubble, reputation"
the justice, a pompous, well-fed middle-aged man
the "lean and slippered pantaloon" – an old man, thin and feeble, with a reedy voice
and lastly, second childhood and the "oblivion" of senility, when teeth, eyes and, finally "everything" fades away.
The speech had a special appeal to the Elizabethans, with whom the metaphor of "world as stage" was very popular. Even today, its grim humour and vivid word-pictures make it one of the best remembered passages in Shakespeare.
