I Think I Am

 "I think, therefore I am." --Rene Descartes, 17th century French philosopher ["Cogito ergo sum"/"Je pense donc je suis"] 

 "I think, therefore life is more difficult." 😏😉 -- Marie Byars, 20-21st century American dilettante 

 " 'I Think, Therefore I Am Misunderstood.' " --Newsweek article title; 15 October, 2006 

Why is René Descartes considered a thinker? Because he is. 😏 (Ponder that one!) 

 "I think, therefore I have anxieties." -- The sufferer of anxiety disorders 

 A horse walks into a bar and the bartender asks, “why the long face?” The horse morosely replies, “my wife wants a divorce, she says I’m an alcoholic.” The bartender asks if he is, and the horse answers, “I don’t think I am” and promptly vanishes from existence. 

 A guy walks into a bar. The bartender is a horse. He says, "Oh, hey Rene, you want the usual?". Rene says "Yeah sure. Why the long face?". The horse and bar disappear because they were never, in fact, real and the only thing that definitely did exist was Rene. 

Did you hear about the philosopher who was trampled? It was a tragic example of putting Descartes before the horse. 

Waitress: Sir, do you want one more coffee? Descartes: Umm..I think not. And he disappears. "I don't think so", said René Descartes. Just then he vanished. 

Rene Descartes comes into a bar. He orders a really old and expensive bottle of wine and after a couple of hours when he's done drinking it, he stands up from his chair, planning to leave. The bartender stops him: "Sir you have to pay for this!", Rene stops and says, "I don't think so" and disappears. 

A man offers Descartes $100 to jump in a lake. Without thinking, Descartes ceases to exist. 

Rene Descartes walks into an empty room... After some time he remarks, “Is it solipsistic in here, or is it just me?” (for the advanced philosopher 😏 ) 

What do you call an empty, self-aware 2-dimensional space? Descartes Blanche
