In the recently released Ruthless Aggression documentary series, John Cena was seen talking about his WWE debut and how the persona of 'Dr. of Thuganomics' saved his career. The persona resonated with the hip-hop generation of the 2000s and attracted a huge fan base. It even helped John Cena save his job and become the biggest wrestler to come out of the Ruthless Aggression Era. Despite his success, John Cena once went to Vince McMahon’s office and told him that he would stop rapping in WWE.
In the documentary, John Cena revealed that the persona of 'Dr. of Thuganomics' attracted many, but after a few months, his fan base changed. He admitted that at first, he used to resonate with youth and adults. However, now he used to attract more kids and parents. He said that he used to see a lot of kids wearing his clothes, more than adults. That’s why he went to Vince McMahon and told him that he won’t rap anymore. He said kids don’t resonate with rapping and that’s why he stopped it.
“I didn’t need a sheet of analytics. I can see it. So I said, this is it. We’re changing up right now. I remember going into Vince’s office and said, ‘I have to stop rapping,’” said John Cena.
John Cena’s last appearance as 'Dr. of Thuganomics' was almost a year ago at WrestleMania 35 where he interrupted Elias' concert. During the segment, he insulted Elias with rap and joked about turning heel. He then performed his finisher on Elias but called it by its original name, the F-U.
