+Imagine a man coming out of a bar in cancun, an open bottle of sunscreen dribbling from his back pocket. He walks forward for a few steps, and then there’s a good chance that he will stumble in one direction or another.
+Now put that guy on a big canvas with an X and Y dimension.  The line his sunscreen drippings will make is a random walk.
+The math behind that chaotic process is pretty useful in all kinds of domains, option trading being one in particular.
+"How do we model this stock"
+"Imagine it's running around like a drunk guy in Cancun"
+"Cool"
