Suppose the Mullahs gave a demonstration and nobody came...

Well, according to this report, that’s exactly what happened when they tried to fan the flames of the GMCC (Great Mohammed Cartoon Controversy):

The organized rallies were intending to show, what was supposed to be, the massive indignation of Iranians over the publication of cartoons depicting the Islamic Prophet Mohammad. But despite all supports from governmental circles and advertisements made by Mosques related to the theocratic regime, which had called for a massive participation, the demonstrators stayed under 400 individuals while the Iranian Capital has over 12 millions of inhabitants.
