...were all having a pleasant message board conversation when the subject of great inventions came up. Gunny, never short on opinions, immediately piped up with "the computer is easily the greatest invention of all time. Just think of how it's revolutionized the world. Heck, we wouldn't be sharing our collective wisdom right now without it." Then Diuretic, the philosopher realist, says "slow down charlie, electricity is the greatest invention of all time. Without it, your computers would be useless!" Then Shogun, never to be out-witted, says "pffft! You're both idiots and I'll prove it with my 'facts' & 'evidence.' The thermos is by far the greatest invention of all time. Why you ask? Because it keeps hot things hot and it keeps cold things cold, that is why." Both Gunny and Diuretic reply with a collective "so?" And finally Shogun says "How does it know?"
