A horse walks into a bar. The bartender says, “you’re in here alot, 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
