A terrible thought has moved into my mind
  Like an unwanted room-mate drunk on wine
  It feeds on my happiness won't pay the rent
  I must take proper measures to evict it
  
  A terrible thought has moved into my mind
  A giant rat that's nibbling on my pride
  It's tearing away my patience and my wit
  I must take proper measures set a trap for it
  
  What a terrible thought
  
  I don't care what you've done
  I don't care who you've won
  I know in the end you'll have your fun
  
  But you can't have it hear
  And I won't let you steer
  You know I don't want you in my mind
  
  I must stay calm you know and I must be clear
  It's gonna take a hundred thoughts to make this one disappear
  A train like that could travel a soul for years
  A terrible thought could have a terribly long career
  
  What minds have you shredded
  I bet they regretted
  Having ever thought you up
  Just look at you shine
  Commiting your crimes
  You know I don't want you in my mind
  
  'Cause you're breaking my stride
  You poisonous vine
  You're strangling me inside
  You're breaking my stride
  You poisonous vine
  You're strangling me inside
  You're breaking my stride
  
  What a terrible thought...
  
  Father :
  What is your greatest worry because you seem to be worried all the time
  
  Daughter:
  Sometimes I can't hear myself think
  
  Father:
  YYou have to speak a little louder,
  I can't understand a word you're saying
  
  Daughter :
  Sometimes I can't hear myself think
