We went to the zoo   We learned a thing or two   Animals die just like you and I   Even bears have heart attacks   And even lions have heart attacks      There's no need to cry, Mother Nature tries   And even cows have heart attacks   And even baby dinosaurs have heart attacks      They don't exercise and they eat too much fat   And even leprechauns have heart attacks   And even Nostradamus had heart attacks (I knew it)      It's just nature's way, it happens every day   And even Bob Marley cover-bands have heart attacks   Even cheerleaders, trees, and birds have heart attacks      If we knew why, we'd know the meaning of life   If they'd just exercise maybe they'd survive their heart attacks!
