A horse walks into a bar; the bartender asks, "Do you want a beer?"
The horse responds, "I think not," and promptly disappears.
Now, admittedly, this joke only makes sense if you consider the French Enlightenment philosopher, Rene Descartes, who famously said, "I think, therefore I am." The horse thought not, and therefore wasn't....
But if I had mentioned that first, I would have been putting Descartes before de horse.

I achieved complete enlightenment after eating a delicious sausage made from the meat of a South American camelid.
