Mexican fans and their contribution to football culture are simple to spot. At certain points of sports events, sections of a stadium crowd will suddenly stand up, wave their arms in the air, roar for their team and then sit down again. Others next to them jump to their feet seconds later. The combined movements look like a wave, rippling around the stadium.
"The Mexican wave" went global at the 1986 World Cup in Mexico. While there may have been waves before, this was the first time " La Ola", as the Mexicans call it, featured widely on TV.
While Mexicans will no doubt be making waves in Germany, another famous export may not be appearing. Mexican TV"s celebrity clown Borzoi, the creation of comedian Victor Trujilo, reported from the last three World Cup"s. Trujilo stopped playing the character after his wife"s death in 2004.

Last week he complained about being left off the team, saying there was "no valid argument" for leaving him behind.
