Am I the only person in the world that understands this?

Who said this? It's one of my favourite speeches of all time.

There are known knowns, they are things we know we know

There are known unknowns, that is to say, we now know things we did not know.

There are unknown unknowns, there are things we do not know we don't know.

(Makes me laugh, but it makes logical sense albeit convoluted)
