Did you know rousseau

Did you know Rousseau?
Did you laugh in his face?
Did he smile, did he nod,
And did he paint the next day?

Did you go to his house,
To wink while he played?
Was Picasso there,
And did did Picasso say,

"If you dream of a tree,
Does if have to be wood?
Have you not, known a knee,
That didn`t bend like it should?
Here we see, a world, where tigers play,
Don`t you wish you could stay?
Well I do, I do,
And Rousseau knew."
