An astronomer says to a minister, "Preacher, you minister-types always make the Bible and being a Christian unnecessarily complicated with all your biblical exegesis and theological and ecclesiastical doctrines. Humbug. It's all very simple. Do unto others as you would have others do unto you. That's all you need to know and all you need to do." Well, the minister thought for a second and then answered. "You know, I'm glad you raised that issue. I've been thinking about astronomy and astronomers with all your theories about an expanding universe and black holes and myriad galaxies. We don't need all that scientific mumbo jumbo. Astronomy is actually quite simple and can be summed up in a few words. Twinkle, twinkle, little star. How I wonder what you are."
