Abramović was just leaving a book-signing at the Palazzo Strozzi in Florence when Vaclav Pisvejc approached her with a framed portrait he painted of her. She thought he was bringing her a present; instead, he lifted it high, smashed it over her head, and said, “Boom!” When Abramović, unhurt (there was no glass over the frame) asked Pisvejc why he would do this, he replied, “I had to do it for my art.” (includes video)
