what trick does the lord plan to play on sly

The Lord decides to play a trick on the drunkard Sly. He tells his servants to carry Sly to his own noble chambers and pretend that Sly is in fact a lord. Soon afterward, a troupe of Players arrives at the Lord's house, intent on performing that night. The Lord informs them that "a lord" is visiting the house and will hear them play, and warns them of his "odd behavior." In the meantime, the Lord orders that his page masquerade as Sly's wife. The page will then pretend that Sly has been afflicted by lunacy for many years and has dreamed himself to be no better than a lowly tinker.
