Rene Descartes walks into a bar.
A horse walks into a bar.
The bartender says: "I thought the horse came before Descartes."
Rene Descartes is sitting at the bar.
The bartender asks him: Will you be having a drink?
Rene Descartes says "I think not" and disappears.
Fantastic. Only good laugh today, and I needed it. Merci.
