Thanks for the laughs, Rummy.

I know this quote is super old, but it's just classic.

The Unknown
As we know,
There are known knowns.
There are things we know we know.
We also know
There are known unknowns.
That is to say
We know there are some things
We do not know.
But there are also unknown unknowns,
The ones we don't know
We don't know.

I'm putting together a talk on fresh produce outbreaks for a conference later this week and one of my co-workers suggested I include this quote for a bit of levity, since there is a lot about fresh produce outbreaks that is, in fact, unknown. However, I don't think I should introduce myself to the communicable diseases community of Australia with a quote from Donald Rumsfeld.

Besides, I'd be laughing too hard to continue with my talk.
