nonsensical bantering or definite metaphor?

ok so this riddle in the lyrics of "into the woods" by My Morning Jacket has been finding its way into my conscience for the past several weeks, seeing that it is never going to leave me alone whats your take on it? (and maybe bother the hell out of you)here are the lyrics straight from the MMJ official site"A KITTEN ON FIRE. A BABY IN A BLENDER. BOTH SOUND AS SWEET AS A NIGHT OF SURRENDER.I KNOW IT AIN'T EASY - BUT YOU DO WHAT YOU CAN. IF YOUR LIVIN GETS WEEZY - YOU CAN FOLLOW THIS PLAN:PUT IN MORE THAN YOU COULD EVER GET OUT. I'M TIRED OF THE TALKING - I KNOW WHAT YOU'RE ABOUT.NOW OPEN YOUR MOUTH - HERE COMES THE SPOON. YOU'RE GONNA EAT WHAT I GIVE YA -AND YOU'RE GONNA LIKE IT REAL GOOD.1. A RIDDLE: I WENT OVER THE RIVER - AND INTO THE WOODS - WHERE DID I GO?WHERE A WOOD BURING STREAM FLOWS UP THRU THE TREES -LIKE THE SOUL OF THE HOTTEST KIND OF LOVER I'VE EVER SEEN: "E"ONE WHO LIVES TO CHOOSE ANOTHER FOOL'S DREAM.A GOOD SHOWERHEAD AND MY RIGHT HAND - THE TWO BEST LOVERS THAT I EVER HAD.NOW IF YOU FIND YOU AGREE WITH WHAT I JUST SAID, YOU'D BETTER FIND A NEW LOVEAND LET 'EM INTO YOUR HEAD."
