Scratch a dog and you'll find a permanent job
Franklin P Jones

If you can resist treating a rich friend better than a poor friend, If you can face the world without lies and deceit, If you can say honestly that deep in your heart you have no prejudice against creed, color, religion or politics, then, my friend, you are almost as good as your dog

The dog is a yes-animal, very popular with people who cant afford to keep a yes-man.
