"I don't know what isn't going on"

"I don't know what isn't going on",  

a doodle by JVL drawn during a Course Review Committee meeting at Brighton Polytechnic, 

and published in Drawn to Drawing, Nobrow Press, 2014, page 222.

The statement is a double negative perpetrated by the person in the chair at the time. But a better one than this was when a different person said, at another meeting - "Don't think that I am not unaware that nothing isn't going on here" - a glorious quintuple negative!
