What Is This Thing Called Love?

I was a humdrum person
Leading a life apart
When love flew in through my window wide
And quickened my humdrum heart

Love flew in through my window
I was so happy then
But after love had stayed a little while
Love flew out again

What is this thing called love?
This funny thing called love?
Just who can solve its mystery?
Why should it make a fool of me?

I saw you there one wonderful day
You took my heart, threw it away
That's why I ask the Lord in Heaven above
What is this thing called love?

I saw you there one wonderful day
You took my heart, tossed it away
That's why I ask the Lord high in Heaven above
Tell me, tell me what is this thing
Oh, I mean this funny thing
Oh, yeah this crazy thing
Called love
