This song by Hank Green contains only ten words. Thanks to zowix for sending in.

I don’t think you know what you think you know, baby.
But baby, don’t you think that I know what I know, maybe?
Baby, I know what you think that I don’t know.
I know, I know, I know, I know, I know.
I know, I know, I know, I know, I know.

I know that you don’t think I know that I know what I know.
I don’t know what you think I think; I think you know I don’t.
But I know what you don’t think I know; I know, I know, I know.
Baby, I know that you don’t know what I know.
Baby, I know that you don’t know what I know.

I don’t know what I think, but I know what I know.
But you think that you know what I know that you don’t,
That I know what you think I don’t know.
I know, I know, I know, I know, I know.
I know, I know, I know, I know, I know.

I know that you don’t think I think that I know what I know.
I don’t know what you think I think; I think you know I don’t.
But I know what you don’t think I know; I know, I know, I know.
Baby, I know that you don’t know what I know.
Baby, I know that you don’t know what I know.
