Two Halves Make a Whole lyrics

We've only just met
We've barely said a word to each other yet
But already I know that
We fit
Yes, two halves make a whole
And wholes are whole
Like an arm through a sleeve
Or a cup into a movie seat
You haven't said a word to me
Only just giggled gleefully
But already I know that
We fit
Yeah, we fit
You're kissing my space helmet
And already I know
That two halves make a whole
