I don't know where you came from   I don't know how   You got underneath my skin, I can't get you out   Why can't I hang on to my senses   I try and I try but it makes no difference it's      Illogical, uncontrollable, impossible boy how can it be   what you do to me   It's so irresistible, unpredictable, unstoppable   and I can't help but fall   If this is what you call undeniable      Maybe I think too much I overanalyze   My heart is feeling what my head wants to deny   What's done is done and I can't ever change it   I'm so far gone and I don't know how to explain it - it's so      Illogical, uncontrollable, impossible boy how can it be   what you do to me   It's so irresistible, unpredictable, unstoppable   and I can't help but fall   If this is what you call undeniable      The snow will fall in winter, the moon will pull the tide   some things will never change so why even try      Na na na na na na na   Na na na na na na na      It's so   Illogical, uncontrollable, impossible boy how can it be   what you do to me   It's so irresistible, unpredictable, unstoppable   and I can't help but fall   If this is what you call undeniable      Illogical (na na na na na)   Uncontrollable (na na na na na)   Impossible (na na na na na)   (What you do to me) (Undeniable)   Irresistible (na na na na na)   Unpredictable (na na na na na)   Unstoppable (na na na na na)
