I know there's things you never thought before
That have to do with walkin' out old doors
You've been prepared as long as time allowed
Well I don't know how
But you're a big boy now
Come on and take a bow
Cause you're a big boy now

You know the girls are taking notice of you
They say your hair is getting curly too
So shave today you'll shave tomorrow as well
You're run by you and not a class-room bell
And I don't know how
But you're a big boy now

And the great big world daddy threw before you
With the pretty faces and the claws that tore you
And it's all so different when you get to sources
And love will make you strong
as a team of wild horses

I know there's things you never thought before
That have to do with walkin' out old doors
You've been prepared as long as time allowed
Well I don't know how
But you're a big boy now
Come on and take a bow
Cause you're a big boy now
