Well, Colombus DID discover America. He just 1: wasn't the first (well, the indians had been there a while, eh? And mr Erikson discovered Canada) and 2: Thought he was somewhere completely different (which is why the native americans are named "indians").
Now, if we could all agree that mr Colombus was the first captain in the world to embark on a cruise to the Caribbeans, maybe we could just get on with our Amiga lives :-D
