What joke involved a goose and a lawyer?

One classic joke involving a goose and a lawyer goes like this: A lawyer was driving down the road when he saw a goose standing by the side. He stopped and said, "What are you doing here?" The goose replied, "Just trying to find a good quack!" The punchline plays on the double meaning of "quack," referring both to the sound a goose makes and to a fraudulent doctor, poking fun at the legal profession.
