If you cheat in South Park: The Fractured But Whole, the game will call you Tom Brady. The moment unlocks specifically if you choose to type in the code to Cartman's layer without first going upstairs to read Cartman's diary to obtain it. Take a look:
In case you aren't the most avid follower of NFL football, Cartman is dressed up as New England Patriots coach Bill Belichick and Tom Brady is the Quarterback of the team.

The controversy ended in a whole lot of drama that resulted in a suspension which was overturned by courts, and then overruled by the NFL. Tom Brady was suspended for four games in the opening season which ultimately led to the Superbowl in which Brady successfully lead the Patriots to the greatest comeback victory ever seen in NFL history. It also led to this uncomfortable press conference in which NFL commissioner Roger Goodell (who handed down the suspension) was forced to award Tom Brady with the Super Bowl MVP trophy later that season:
