In 1999, I went to Carnaval in the Sao Paulo Sambadrome. Good time... = ) Beside that, the Escola De Samba Vai-Vai did a "Nostradamus" theme. Predictions of the future and wars and such. One group in the school was dressed as Silver coated Nazis. Swastikas and all, including a silver, black and red Nazi Herald (emblem ) carried by the group. The like-dressed "Nazi samba dancers" were an "enigma" I barely remember. Dang, it sounds like the title of a "Troma" movie...
We were all so wasted we didn't think about it much. My passing thought was "You just don't see that every day" and later "That was probably a bad idea". It hit all of the broadcasts the next day, some people complained. The Brasilians brushed it off say "It's Carnaval!".
