We've been building something fine, it seems like forever
Could be intelligent design, but we're really not that clever
Now it's back to the drawing board, back to going by feel
Back to when falling in love was reinventing the wheel
Reverse engineering, taking the pieces apart
To find the bit that's made to fit what's missing in your heart
Reverse engineering, that's what I try to do
When I'm losing track and can't get back to what's going on with you
What's going on with you
So we've been going by the blueprint, with ciphers writ in white
We can trace out every bone-like line, but the flesh is out of sight
There's no patented invention, no prototype for this
But I parlay my intention for a magic-bullet kiss
Reverse engineering, that's what I try to do
When I'm losing track and can't get back to what's going on with you
Reverse engineering, taking the pieces apart
To find the bit that's made to fit what's missing in your heart
What's missing in your heart, missing in your heart, etc
