Having abused Desdemona, an enraged Othello, thinking she is having an affair with Cassio, turns on Lodovico with the following speech, saying:

Yes, you asked me to call her back. See how well she can turn? She can turn and turn, and then turn on you again. And she can cry, sir—oh, how she can cry! And she’s obedient, as you say, obedient. Very obedient—keep crying.—Concerning this—oh, what fake emotion!—I am being ordered home—Get away from me, I’ll send for you later.—Sir, I’ll obey the order and return to Venice. Get away from me, you witch! Cassio shall have my place. And, sir, tonight

I do entreat that we may sup together.

You are welcome, sir, to Cyprus. Goats and monkeys!

Othello's reference to "goats and monkeys" in Shakespeare's play is a sign that his mind is beginning to break down - he is treating his own wife, a girl that he has no reason to think is not totally pure, as a fallen woman - Iago's constant pressure is beginning to pay off. Different animals had different connotations in Shakespeare's time and monkeys had been referred to as "hot" or, in our terms, being morally "loose" and full of licenscious animal drives and passions.Othello, it seems, has little experience with women and is very black and white when it comes to categorizing them. This is because armies were an all-male preserve for a lot of the time, and travelled away a lot. Men were more like likely to believe an old comrade in arms than a girl they had just met, simply through the life-saving attachments they had built up.
