Monkey Business
A man spent several years of his life saving to buy a monkey. After buying the monkey and testing it out, he decided that what he really wanted was a bear. He found that he could trade in the monkey, so it wouldn’t take him quite as long to get the bear as it did [to get] the monkey. A few years later, he finally had enough to buy the bear. Later, he couldn’t find a place for the monkey or the bear and couldn’t use them, so he exchanged them and settled for a dog. Now he’s thinking that perhaps some day in the future he may even get a cat, but the dog is good enough for right now.
