After a long (really long) wait, Ubisoft finally released South Park: The Fractured But Whole, the new turn-based RPG style game starring televisions most vulgar cartoon fourth graders. Fans of the show will be treated to plenty of Easter eggs and inside gags stemming from the 21 seasons of the award winning cartoon, but here’s one that many people might miss, assuming they are playing the game properly.

Early in the game, you are required to get into Cartman’s basement, which is locked with a keycode. The code can be found upstairs in Eric’s bedroom, but if you use a walkthrough (or simply watch the Kotaku video above), you’ll know that the code is 307 — or “F**k You Mom.”

But the game knows whether you’ve already searched the bedroom or not. If you are taking a shortcut, Cartman pops up (dressed like Bill Belichick) and berates you for cheating, even calling you “Tom Brady.” It’s actually pretty hilarious.
