A horse walks into a bar and after a few drinks the bar tender calls out to the nag;
"Excuse me, do you think by chance you might be an alcoholic?"
The horse ponders this for a moment and says;
"I don't think I am."
Then poof the horse disappears.
[now for anyone not following, this is funny because Rene Descartes famously postulated, 'I think therefore I am'. And because the horse didn't think he was, he wasn't.
I probably should have led with the explanation about the philosophy but I didn't want to put Descartes before the horse.]
