Testifying at a hearing during the investigation of his company's alleged voicemail hacking, media executive Rupert Murdoch nearly received a shaving-cream pie in his face. Some on Twitter saw it coming. Pie slinger Jonnie Marbles (real name Jonathan May-Bowles) hinted at his attack in a tweet (@JonnieMarbLes) just minutes before he disrupted the hearing. The attack was foiled by Murdoch's wife Wendi Deng and several others in the courtroom who tackled the self-described "activist and comedian" after his statement. The 26-year-old was arrested and sentenced to six weeks in jail for his actions. And while no physical attack can be condoned, the stunt was the year's shining moment in live Twitter theater.
