Because : . 1. Our nose smells, tells us that there's something fishy . 2. Nose instructs through our brain to the feet to run.. 3. Now even our feet smells that there is something fishy and starts to run.. 4. Eventually the nose also runs along-with the whole body as the feet run!!. . So the conclusion, Noses run and feet smell!!. . hhhheeeeeeee...... . Regards,. Dave M!
