How cool! When I was a little girl, the brother of an elderly woman on our street had one.
When he came to visit, he always let the kids in the neighborhood look at him and would let him sit on our shoulders. He had a bad habit of crapping down our backs

(The monkey - not the man

)
He escaped one day and everybody in the neighborhood watched while the man tried to get him to come down from this huge pecan tree in her backyard.
He finally bribed him down with a treat and we never saw the monkey again.
