My uncle invited Benoit Mandelbrot over to his house once. He sent his son to pick Mandelbrot up at the airport, only he didn't know what Mandelbrot looked like. So he drew an approximation of the Mandelbrot set on a sign and held it up. Sure enough, the mathematician recognized it and was able to find his ride.
