10 Best WWE Easter Eggs In WrestleMania's Firefly Fun House Match

10. Ruthless Aggression

After Cena's entrance in the WWE Performance Center is interrupted by Vince McMahon's introduction at WrestleMania and "Mean" Gene Okerlund's at WrestleMania IV, the leader of the Cenation finds himself face to face with the puppet version of the WWE Chairman who repeatedly hammers home the idea of "Ruthless Aggression."

That's obviously a reference to the promo the real McMahon cut back in 2002 to kick off the era of the same name, and Wyatt makes some very pointed references to Cena's role in that.

The recent Ruthless Aggression documentary on the WWE Network saw Cena admit that his original gimmick was a failure. Well, Wyatt takes a shot at that saying, "Whoever thought this was actually going to work?" while poking fun at Cena nearly getting fired.

However, perhaps the most effective Ruthless Agrression Easter Egg comes when Cena makes his entrance in front of the giant fist which was the centrepiece of SmackDown's stage at the time, and something fans of this era have definitely missed in the years which have followed.
