Microsoft CEO Ballmer was pelted with eggs during a speech (video): probably Apple fans.

The incident took place at a university in Hungary. Balmer was asking questions when suddenly a person who looked like a student stood up and shouted angrily at Balmer, accusing him of stealing money from Hungarian taxpayers and demanding he pay it back immediately. Balmer seemed not to have understood and just stood there (possibly because the student's accent was too strong). Then, Microsoft CEO Balmer was hit by an egg. Please see the video below:
