The Simpsons has offered tongue-in-cheek support to rival show South Park after the creators upset a radical Muslim group. South Park's Trey Parker and Matt Stone received a death threat from a radical Muslim group after they depicted the Prophet Mohammed inside a bear suit. The Simpsons referred to the row with a message written by Bart on his school's blackboard during the title sequence. In an episode just aired in America, the mischievous lad is seen writing in chalk: "South Park - we'd stand beside you if we weren't so scared."
