[LastBestPlace] a horse walks in to a bar humor

A horse walks into a bar. The bartender says "You're in here a lot, are you an alcoholic?"

The horse ponders for a minute and responds "I don't think I am." And poof he disappears.

This is where philosophy students start to snicker, as they are familiar with Descartes postulate "I think, therefore I am."

But telling you that first would be putting Descartes before the horse.
