I, I, I How did you get so sly? I, I, I How did you get so sly? I know no one's perfect But you were nothing like you claimed to be It's still a mystery How do you live like that?

What a waste of my time You live a double life I swear you should go work for MI5 Cause you wear a disguise Almost all of the time How did you get, you get so sly? I should have saved all my energy You were a waste of time Cause I sort of pathetically Thought that you were mine Oops, my mistake And I'm ashamed that I fell for all your lies A mistaken identity How did you get so sly? I, I, I How did you get so sly? I, I, I How did you get so sly?
