No, this is not a Clinton joke.
An artist (Justine Lai) did a series of painting depicting her being filibustered by various U.S. Presidents. If you click on this link, you will see her explanation, NOT the work. If you want to click on the works from there....well, as Tofe says, what is seen on the internet cannot easily be unseen.
I'm not sure what this is about. On the other, she made me look, and wonder, and so that is likely a win for her.
