There is a major difference here. Columbus was seeking riches and most people thought he was nuts. And the Indians almost snacked upon him. DMND was seeking riches in snacks and turmed out to be nuts. It's close but not the same thing.
Even Columbus was wrong when he reached the West Indies. He didn't know where the H--- he was. And he was late as usual because the Indians were already here. Even the Vikings beat him to America by one century. So much for Columbus.
