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.
