I knew on that first night, sippin' that cherry Sprite
Half of the things that you said were a lie
I still thought you were cute, so I listened to you
Tried to convince me that man never walked on the moon

A little bit condescending
But I'm a hypocrite for pretending
That I liked you

You're such a know it all
Whatever game you think you're playin', I got the ball
You think that just because I'm blonde and I'm nice that I wouldn't think twice
You're wrong, I've known it all along
No, you don't know it all, all
No, you don't know it all, all

Shouldn't be playin' dumb, but it's a little fun
Hangin' on every word rollin' off your tongue
Talkin' 'bout politics, thinkin' I'm into it
Well, bless your heart, at least it's good that you have confidence

You're such a know it all
Whatever game you think you're playin', I got the ball
You think that just because I'm blonde and I'm nice that I wouldn't think twice
You're wrong, I've known it all along
No, you don't know it all, all
No, you don't know it all, all

I know you mean well
It's sad you can't tell
That you're actin' like I never even learned how to spell
D-O-N-E, you and me are done
Yeah, we're done

You're such a know it all
Whatever game you think you're playin', I got the ball
You think that just because I'm blonde and I'm nice that I wouldn't think twice
You're wrong, I've known it all along
No, you don't know it all, all
No, you don't know it all, all

You're such a know it all, all
