My Turquoise

Is Act III, Scene i of the Merchant Shakespeare's best? Arguable. Although Twelfth Night's 2-iii is priceless as well. Not to be abed after midnight is to be up betimes. Nevertheless. The villany you teach me, I will execute, and it shall go hard but I will better the instruction. And culminating with this brilliant slice:

TUBAL
One of them showed me a ring that he had of your
daughter for a monkey.

SHYLOCK
Out upon her! Thou torturest me, Tubal: it was my
turquoise; I had it of Leah when I was a bachelor:
I would not have given it for a wilderness of monkeys.
