Note that there are studies that suggest a possibility of polynesian peoples traveling to South America around 1200 CE.

Some 20-25 years ago on a local radio FM station they used to run a “bumper” from time to time of a narrator saying that one time in WWII Nazi Germany sent a decrepit train full of excrement, trash and whatnot to neutral Switzerland, trying to tease them and make them join the war. In rensponse Switzerland cleaned, fixed and painted the train, put fresh food and flowers and everything and sent it back to Germany and in the engine they put a giant banner reading “each one gives the best of themselves” or something like that - pretty sure that story was just a myth but at those times when I heard it I wished it was true because it was so fucking funny.
