A horse walks into a bar...

The bartender asks the horse if it's an alcoholic, to which the horse replies, "I don't think I am." Poof! The horse immediately disappears.

This is a joke playing on the fundamental philosophical proposition of “cogito ergo sum”, or "I think, therefore I am."

I would have explained that first, but that would have been putting Descartes before the horse.
