In the Post a video, enteratin me! thread, farley3k posted a video where a guy talked about things he was taught in school that have been debunked.
It made me think about how I got into an argument about the number of continents because I was taught there were 5 in Canada but in the US it is taught that there are 7. For the record they are Africa, America, Australia, Eurasia and Antarctica.
Please share the ones you have come across.
