I'm a mathematical function, the world flows in and out of me all of the time. I'm a cogs and wheels machine, don't be fooled by this flesh of mine. My motions are equations, though they appear as a rabid dog. They come out like a flick of an eye, but if you're quick you can predict mine. It's smooth, though I have a feeling you already know what I want. I'm twisting and turning, and twisting and turning, and twisting and turning, and twisting, Oh happy, happy, happy, My love, my love, my love, Oh sunshine, blue sky, sunshine, Oh yeah, Oh crying, crying, crying, Crying out loud, Oh happy, happy, My love, my love, my love, Oh the hunger, the hunger, the hunger, Oh the hunger in my heart, When I kill the hunger in my heart, My leg leaps up in alarm, I need constant feeding, The hunger never leaves, Oh I once read a story of a man from the east, Who starved himself and he found peace, But not me, Oh but not us here, We're twisting and turning, and twisting and turning, And twisting and turning, and twisting and turning, And twisting and turning, and twisting and turning, And twisting and turning, and twisting and turning, And twisting and turning, and twisting and turning, Oh happy, happy, happy, My love, my love, my love, Come with me, I'll find you, Oh crying, crying, crying, Crying out loud, Oh happy, happy birthday, Happy Tuesday, Happy birthday, Happy Tuesday. Happy birthday to you.
