Not only did the Chiefs best a hated division rival and move to 6-0, but Kansas City managed to set a world record in the process.
Actually, it was the fans in Kansas City who set the record.
Prior to the game, a small group of these fans organized a movement to set a new Guinness world record and to reclaim Arrowhead Stadium's title of loudest stadium in the NFL.
“We want the fans being as loud as ever and we’re doing everything we can to break a world record and to reach 137 decibels,” Ty Rowton, one of the group's members said, via KCChiefs.com.
Once the dust finally settled on Sunday, the Chiefs had earned a 24-7 victory over Oakland and a 137.5 decibel victory in the stands.
It's difficult to argue that this season could be going any better for Chiefs fans. After watching their team stumble to a 2-14 record in 2012, they can now cheer for a team that boasts a perfect record.
According to Guinness, Chiefs fans have cheered their team into the record books.
