Another example of 19th century man slang:
Blind Monkeys: An imaginary collection at the Zoological Gardens, which are supposed to receive care and attention from persons fitted by nature for such office and for little else. An idle and useless person is often told that he is only fit to lead the Blind Monkeys to evacuate. Another form this elegant conversation takes, is for one man to tell another that he knows of a suitable situation for him. "How much a week? and what to do?" are natural questions, and then comes the scathing and sarcastic reply, "Five bob a week at the doctor's-- you're to stand behind the door and make the patients sick. They won't want no physic when they sees your mug."
