Al's joining the Flat Earth Society as well! What's all this nonsense about the world being round? You'd fall off.

(I had a prof who claimed to be a Flat Earther and could destroy ANY argument against it made by any student. Of course, he was pulling our legs--he had been a navigator in the Merchant Marine in the War and either he HAD to know that celestial navigation could only work if the Earth is round, or....he got his ship lost all the time! They didn't have GPS then, only sextants, stop-watches, compasses, charts, and sight-reduction tables.)
