LORD
Sirrah, go you to Bartholomew, my page,
And see him dressed in all suits like a lady.
That done, conduct him to the drunkard's chamber,
And call him 'Madam,' do him obeisance.
Tell him from me, as he will win my love (Induction.1.110-114)
The Lord's decision to "cast" his page (a young servant boy) in the role of Sly's trophy wife calls our attention to Elizabethan stage, where all characters (male and female) were played by men or boy actors. Bartholomew was likely played by an attractive young boy, one pretty enough to convince Sly that he is a woman. We're supposed to laugh at Sly for being fooled but Shakespeare also points to the slipperiness of gender on stage.

LORD, to Servingman
Sirrah, go you to Bartholomew my page,
And see him dressed in all suits like a lady.
That done, conduct him to the drunkard's chamber,
And call him 'Madam,' do him obeisance. (Induction.1.110-113)
Bart plays a very brief but important role in Shrew. The fact that it's so easy for him to pass as a woman suggests the fluidity of gender ("femininity" and "masculinity"), especially on stage.
Quote 6
LORD
Take him up gently, and to bed with him, (Induction.1.75)
The physical movement from the tavern to the Lord's house traces the disparity between Sly's status as a poor beggar and the Lord's status as a landowner and nobleman. (It also says a lot about the flexibility of the physical stage.)
