Mexicans in South Africa can't be blamed for feeling a little left out. One of the country's leading fast food outlets has run an advert offering free lunch to Mexico fans - as long as they lose.

That's one of the milder ways in which South Africans have declared war on Mexico. Anyone wearing the emerald green of the Central American country are officially enemies of state, but one fan braved the hostility to appear as a guest on a local news channel.

Adolfo Ibarra, a El Tri fan, proudly wore his national team jersey as he entered a Bafana Bafana stronghold. The first question the news anchor put to him was whether the Mexicans could be tripped up by the constant blasting of the vuvuzelas.

He claimed he was "not at all worried," because that the stadium in Mexico City has far more noise as it is able to hold over 100,000 people.

"If you multiply the 10,000 more people the Estadio can hold by the amount of noise each makes, you'll see that there is a lot more noise there. We are not scared of your little vuvuzela," he said, tauntingly. He predicted a 3-1 victory for Mexico and said he expects his team and France to advance from Group A.

His message for South Africans? "I think they are doing a really good job and they should enjoy playing in the tournament. They are guaranteed to play three matches."

Then Ibarra shocked the newsroom by bringing his own blowing horn to the studio. He blew hard and made a noise equal to that of at least three vuvuzelas. He also sang a popular Mexican football chant live on air before leaving. Needless to say, that left the employees in the newsroom, most of whom are behind Bafana Bafana, speechless.
