The Taming of the Shrew by William Shakespeare.

As a joke, a beggar is carried, while asleep, to the house of a noble lord and there dressed in fine clothes and waited on by many servants. The beggar is told that he is a rich man who, in a demented state, has imagined himself to be a beggar, but who is now restored to his senses. The lord and his court have great sport with the poor fellow, to the extent of dressing a page to pose as the beggar’s rich and beautiful wife and presenting the supposed woman to him as his dutiful and obedient spouse. The beggar, in his stupidity, assumes his new role as though it were his own, and he and his lady settle down to watch a play prepared for their enjoyment.
