"Everybody Draw Muhammed Day" was the brainchild of Molly Norris, a former contributing artist to Seattle Weekly and City Arts.
Norris was outraged by death threats made toward South Park creators Matt Stone and Trey Parker following their attempts to show Muhammed in their cartoon in the winter of 2010 (depictions of the prophet are considered sacrilege by many Muslims; Comedy Central censored the episode).
To express her disgust, Norris drew a cartoon that declared a new holiday: "Everybody Draw Muhammed Day." The cartoon went viral, and Norris was soon put on an execution hit-list by Islamic Cleric Anwar al-Awlaki (Seattle Weekly also received threats due to its mere association to Norris). That was in July 2010. By September, Norris had disappeared on the advice of the FBI, never to surface in Seattle again.
