We've certainly seen a variety of crashings go down on stage, but a determined protester and undeterred advocate for open source software rudely (albeit humorously) interrupted Bill Gates' speech at Peking University in Beijing, China. Gates, who was speaking on the topic of Innovation in China's future and receiving (yet another) honorary manager title, had his after-party all shook up by an off-kilter open source proponent who reportedly darted across the stage, "loudly shouted against Microsoft's monopoly," proudly displayed a sign of "Free software, open source," and was promptly "tackled by security and removed for questioning." It was suggested that the culprit may have been a member of the Linux Professional Institute, and while we're not exactly sure if Michael Dell would've shown any forgiveness, feel free click on through for a closeup of the sign and the unfortunate aftermath.
