Tiger, tiger, burning 
  bright,
  In the forest of 
  the night,
  What immortal hand 
  or eye
  Could frame thy fearful 
  symmetry?
  In what distant deeps 
  or skies
  Burnt the fire of 
  thine eyes?
  On what wings dare 
  he aspire?
  What the hand dare 
  seize the fire?
  And what shoulder, 
  and what art,
  Could twist the sinews 
  of thy heart?
  When thy heart began 
  to beat,
  What dread hand forged 
  thy dread feet?
  What the hammer? 
  What the chain?
  In what furnace was 
  thy brain?
  What the anvil? What 
  dread grasp
  Dared its deadly 
  terrors clasp?
  When the stars threw 
  down their spears
  And watered heaven 
  with their tears,
  Did He smile his 
  work to see?
  Did He who made the 
  lamb make thee?
  Tiger, tiger, on 
  the mat,
  You're nothing but 
  a pussy cat,
  But damn your eyes 
  and rue the day!
  I have to clean your 
  litter tray.
