Everybody Draw Mohammed Day

Everybody Draw Mohammed Day (or Draw Mohammed Day) was a 2010 event in support of artists threatened with violence for drawing representations of the Islamic prophet Muhammad. It stemmed from a protest against censorship of the American television show South Park episode "201", led by the show's distributor Comedy Central, in response to death threats that had been made against some of those responsible for two segments broadcast in April 2010.
