The Speed of Sound in Seawater - Or So He Sphinx lyrics

I'm not the one you should be approaching All wrapped in riddles Untouched by Consideration Only answers I'm not the one you're after Which creature at first goes on four legs? By mid-day two, by evening three? With each leg added It grows weaker What creature could this be? There are two sisters Close, so close One births the other And in turn she Then bears her sister By what device Could these two sisters be? You're such a fascinating subject Tell me who built you, feline girl Out in the desert What surrounds you? Nothing but rhymes and sand dunes I'm not so sure that we're all alone here I think I'm in love with every one That silken promise so dismissive I think I'll just go home now Our blurring boarders, so confounding Where you begin and where I end Chimera, crossbreed our composition Nothing but rhymes and sand dunes
