I had a prof one time... He said, "Class, you will forget almost everything I will teach you in here, so please remember this: that God spoke to Balaam through his ass, and He has been speaking through asses ever since. So, if God should choose to speak through you, you need not think too highly of yourself. And, if on meeting someone, right away you recognize what they are, listen to them anyway."
