as a reaction to war. As well as being a reaction to the Cold War, the character has been a cipher for the frustrations the Vietnam War raised, and Ang Lee said that the Iraq War influenced his direction. In the Michael Nyman edited edition of The Guardian, Stefanie Diekmann explored Marvel Comics' reaction to the September 11 attacks. Diekmann discussed The Hulk's appearance in the 9/11 tribute comic Heroes, claiming that his greater prominence, alongside Captain America, aided in "stressing the connection between anger and justified violence without having to depict anything more than a well-known and well-respected protagonist." In Marvel: Five Fabulous Decades of the World's Greatest Comics, Les Daniels addresses the Hulk as an embodiment of cultural fears of radiation and nuclear science. He quotes Jack Kirby thus: "As long as we're experimenting with radioactivity, there's no telling what may happen, or how much our advancements in science may cost us." Daniels continues, "The Hulk became Marvel's most disturbing embodiment of the perils inherent in the atomic age." In Comic Book Nation, Bradford Wright alludes to Hulk's counterculture status, referring to a 1965 Esquire magazine poll amongst college students which "revealed that student radicals ranked Spider-Man and the Hulk alongside the likes of Bob Dylan and Che Guevara as their favorite revolutionary icons." Wright goes on to cite examples of his anti-authority symbol status. Two of these are "The Ballad of the Hulk" by Jerry Jeff Walker, and the Rolling Stone cover for September 30, 1971, a full color Herb Trimpe piece commissioned for the magazine. The Hulk has been caricatured in such animated television series as The Simpsons, Robot Chicken, and Family Guy, and such comedy TV series as The Young Ones. The character is also used as a cultural reference point for someone displaying anger or agitation. For example, in a 2008 Daily Mirror review of an EastEnders episode, a character is described as going "into Incredible Hulk mode, smashing up his flat." In September 2019, British Prime Minister Boris Johnson likened himself to The Hulk in an interview with the Mail On Sunday, as political pressure built on him to request an extension to the date of the UK's withdrawal from the European Union. The Hulk, especially his alter ego Bruce Banner, is also a common reference in hip hop music. The term was represented as an analogue to marijuana in Dr. Dre's 2001,
