You're so confusing, it's driving me crazy! One minute, you're a bumbling clod-- With all the grace of a hippo in orthopedic shoes! And the next, you're Prince Charming... And I'm so stunned by your personality-change I get mushy over you! And what's the point, anyway? We both know you're just a consolation prize to me-- Because I can't have the man I really love-- Superman! Who are we kidding, Clark? Our relationship isn't honest... And that's not fair to you. Or me.
