Here’s an oldie but a goodie we found over at The Art of the Prank:
In September 2004, Mexican artist Miguel Calderón secretly placed a TV set in a bar in Sao Paulo (Brazil). At a certain moment, an unannounced soccer match showed up in the screen. Mexico was playing against Brazil. Bar customers, who had no idea about the match, thought that somehow they missed the news. People started watching the match. Brazil lost 17-0.
It was all staged. Calderón had carefully re-edited various past games between both teams in order to create something completely impossible. The piece was shown as part of the Sao Paulo Art Biennal.
