Rene Descartes

I told Debby about a joke I heard and she didn't get it. Here it is.
A philosophy student was enthralled with a lecture about Rene Descartes. The professor was discussing Descartes theory of doubt and how that left one with the uncertainty of existence and most especially the non-actual existence of ourselves. The poor student was up all night wrestling with the thought that he did not exist. The next morning he got up and went to see the professor and he walked into his office and blurted out his fear, "Tell me professor, do I really exist?" The professor turned and looked toward the student and replied in his strong Yiddish accent, "Zo, who vants to know?"
Get it?
It's not as bad as when Randy Harris at ACU will try and test his class to see if they are paying attention. Before he continues a discussion about Descartes he always finds away to talk about horses in philosophy and his students continue to take notes not realizing the absurdity of what he is saying. He then makes the statement, "but let's not get the horse before des cartes." ....... And his students continue to take notes not even thinking about what was just said. And it's a philosophy course.
