It.) (Twice.)". Soon after, in reference to the controversies and terrorist threats surrounding depictions of the Muslim prophet Muhammad in the South Park episodes "200" and "201", the chalkboard gag on that week's The Simpsons episode, "The Squirt and the Whale", read "South Park – We'd stand beside you if we weren't so scared". South Park was parodied in a 2003 Simpsons episode, "The Bart of War", showing a scene with three of the South Park boys Stan, Kyle and Cartman drawn in Simpsons style, with Marge disapproving of Bart and Milhouse's apparent enjoyment of "cartoon violence", and the latter two contemplating about adults voicing children's characters. The 2009 Simpsons episode "O Brother, Where Bart Thou?" has Bart, Milhouse, Nelson and Ralph dressed up as, standing at the bus stop – similarly to the iconic bus stop scenes of South Park –, and Otto using the catchphrase "Oh my God! I killed Kenny!" when he hits Ralph (dressed as Kenny) driving the school bus. Reception The episode received generally positive reviews. Travis Pickett of IGN gave it an 8.5 rating, especially praising Trey Parker and Matt Stone for managing to contrast the episode with the actual Simpsons with themes like Cartman performing fellatio on "some guy in an alley", while respectfully paying their dues.
