Behold the mighty dinosaur, br Famous in prehistoric lore, br Not only for his weight and length, br But for his intellectual strength. br You will observe by these remains br The creature had two sets of brains, br The one in his head, the usual place, br The other at his spinal base. br Thus he could reason a priori br As well as a posteriori. br No problem bothered him a bit, br He made both head and tail of it. br So wise he was br So wise and solemn br Each thought filled just a spinal column. br If one brain found the pressure strong, br It passed a few ideas along. br It something slipped the forward mind br ’Twas rescued by the one behind. br And if in error he was caught br He had a saving afterthought. br As he thought twice before he spoke br He had no judgment to revoke. br For he could think without congestion br Upon both sides of every question. br O gaze upon this noble beast, br Defunct ten million years at least.
