Jack

Who is Jack?
 Jack is in your head
 Who is Jack?
 Jack is in your bed
 And Jack's been reading, Jack knows everything
 And Jack's been havin' little daydreams
 And Jack wants to keep your fingernails clean
 And Jack is sitting at your breakfast table
 Jack is all around
 But you, you can't see
 And Jack knows what you like
 And Jack knows what you hate
 And Jack gets jealous when you slip out on a date
 And Jack is sittin' at your breakfast table
 And Jack will see that you're all alone
 And Jack is sittin' at your breakfast table
 And Jack will see that you're all alone
 Who is Jack?
 He's all around
 But you can't see
 'Cuz Jack protects you
 And Jack is the enemy
 Who is Jack?
 You're caught in his web
 Who is Jack?
 And Jack's been havin' little daydreams
 And Jack wants to keep your fingernails clean
 And Jack is sittin' at your breakfast table
