Frankie Lymon and the Teenagers - I'm Not A Know-It-All lyrics

I'm not a know-it-all, Don't know why the gra** is tall. Don't know why there's morning dew, I only know that I love you. I'm not a know-it-all, Don't know why the raindrops fall. Don't know what's beyond the blue, I only know that I love you. With things that are not of you alone, I'm not so wise. And still I could write a book of my own, When I look in your eyes! I'm not a know-it-all, Yet I know I'll run to you, The very moment that you call. I love you, know you know it all!
