Act 3: What does Feste consider himself to be? Is this true? (Please provide some evidence to support the answer)

Feste is a master of changing language to turn meanings in different directions. He is the master of double entendres. Take, for example, Feste's quip about living near a church:

Feste
No, sir, I live by the church.

VIOLA
Art thou a churchman?

Feste

No such matter, sir. I do live by the church; for I do live at my house, and my house doth stand by the church.
