By Ed Cropley JOHANNESBURG (Reuters) - A fake sign language interpreter took to the stage during a mass memorial for anti-apartheid leader Nelson Mandela, gesticulating gibberish before a global audience of millions and outraging deaf people across the world. DeafSA, South Africa's leading deaf association, condemned the presence of the unknown man at the memorial, which was attended by President Jacob Zuma and scores of world leaders including U.S. President Barack Obama. Besides the bizarre twist to an event that also saw Zuma booed and jeered, the man's presence on the stage within yards of Obama and Brazil's Dilma Rousseff raised awkward security questions. He just invented his signs as he went along," said Delphin Hlungwane, an official sign language interpreter at DeafSA.
