Hyperthyroidism

As I walked, one morning, alone, by the sea, Thinking of nothing but myself and me, I noticed, above the roar of the ocean, A splashing, and thrashing, and foaming commotion. My heart pounded madly, and adrenaline surged, When a great, scaly beast, from the water emerged. The creature stood glistening wet in the sun. I didn't know whether to stand there, or run. It turned its great head and looked all around. Its red eyes like beacons, ten feet from the ground. As it stepped slowly forward, the damp beach sand crunched, And I wondered if I would be breakfast, or lunch. Although the sea monster was at least ten-feet tall, The look in its eyes was not threatening at all. The creature seemed friendly, and curious too-- Wondering and waiting to see what I 'd do. At last I remembered what feet were made for, So I slowly turned, and walked back down the shore. Now, strange as it seems, the thing followed me home. It lay down on the porch, and I ran to the phone. I called up some scientists, and they rolled on the floor, When I said I'd discovered a live dinosaur. But, to prove that they know how to play by the book, They said, "Bring it on in, and we'll take a look." Well, they probed, and they prodded, and they analyzed. They studied its throat, its ears, and its eyes. Then the great men of science, at last, made their call: "Why, this isn't a dinosaur at all! Marine iguana is the correct definition-- With a somewhat serious thyroid condition."
