Ugh. This again?

Kansas City Chiefs fans are trying once again to reclaim their self-applied title as the NFL’s loudest fans. During the Chiefs’ upcoming “Monday Night Football” matchup with the New England Patriots, the Kansas City faithful will attempt to break the 12th Man’s Guinness World Record for loudest crowd roar at an open-air sports stadium.

Seahawks fans, your record is on the line.

Seattle’s Guinness World Record was just one of the many captivating story lines of the 2013 season. Let’s recap.

On Sept. 15, 2013, Seahawks fans set a new world record of 136.6 decibels during Seattle’s Week 2 home matchup with the rival San Francisco 49ers. It was a wild night — complete with a lightning delay — as the crowd of 68,338 watched their Hawks destroy the Niners 29-3 at CenturyLink Field.

Yet Chiefs fans, who long regarded themselves the NFL’s loudest, took issue with the 12th Man’s new title and orchestrated their own attempt a month later. That Oct. 13, as the Chiefs battled the Raiders at Arrowhead Stadium, Kansas City fans reached a mark of 137.57 decibels, breaking Seattle’s record.

Not to be outdone, the 12th Man attempted to break the record again Dec. 2 in a “MNF” game against the New Orleans Saints. Seahawks fans successfully edged their K.C. counterparts by hitting 137.6 decibels on Guinness’ sound meter, reclaiming their title as the Seahawks clinched a playoff berth.

Well, according to Chiefs fans, this isn’t over. Here we go again ….
