Descartes around the watercooler

As deliveries became scarce last night, discussions heated around the watercooler (metaphorically, actually around the dishwasher). The question was posed as to whether or not unicorn's exist. I sided on the assertion laid forth by Descartes, he of "I think, therefore I am fame." I asked Gene, an older gentlemen known for limping and calling Turk's mistress a hoochie to her face, if he has seen wings--"yes"-- what about a horse--"yes"--how about a horn--"yes"--well then what's to say all these don't exist somewhere in the form of a majestical flying horse known affectionately as a unicorn. I also employed the "They didn't know there were red men in a Brazilian rainforest until last week" defense--which seemed to get raised eyebrows. Gene was sold. Marquise, a cook whom Turk calls Usher on account of their likeness, wasn't. His argument rested on the widespread belief on such creatures, basically, he hasn't seen one, so they must not exist. Turk was optimistic, "If unicorns come out, I'm going to get me one of those joints. People will say, hey man, you got one of those unicorns, and i'll say, yeah, I got a white and brown one, picked him up bootleg before they hit the streets."
