Big and I'm bad
   And I want you to know
   I hand around
   Where the grass is greener
   Totally naked, baby
   Totally nude
   'Cause if I want to
   Who's gonna stop me?
   I'm absolutely free
   Living in the trees
   The birdies and the bees
   'Cause I'm a nature boy
  
   Locked up inside
   You can't tell me where it's at
   Open up, open up, open the door
   Rocks and trees and physical culture
   Some days you hide
   I guess you wonder where you are
   Nature boy, nature man, take me along
   We got a life that's undiscovered
  
   We threw it all away
   Throw it all away
   Rolling every way
   It's irresponsible
   So civilized
   I guess you wonder where you are
   Nature boy, nature man, take me along
   Deep in the woods we're undiscovered
  
   I'm a little fish and you're the river
   Living in a boat that's underwater
   We can tip, tip, tip it over
   You can push, push, make it better now
   Wake your daddy up
   It's a quarter to five
   Our little boat
   Has lost it's rudder
   Dive to the bottom
   And we never come up
  
   A polka party
   For Bob and Martha
   I'm absolutely free
   living in the trees
   The birdies and the bees
   'Cause I'm a nature boy
   Think what you like
   This is really where it's at
   Open up, open up, open the door
   We don't need clothes and we don't need money
   So civilized
   I guess you wonder where you are
   Nature boy, nature man, take me along
   Deep in the woods we're undiscovered
