Fat Bear Week: Who will be crowned this year's 'beefiest bruin?'

The beefiest of all bruins are about to vie for the crown to become this year's heavyweight champion, as the 11th-annual Fat Bear Week -- a sensation that captures the attention of millions across the globe -- is set to begin. Fat Bear Week, which started in 2014, is an annual competition where brown bears from Alaska's Katmai National Park face off in head-to-head matchups -- similar to a March Madness bracket -- with people around the world voting for who they believe is the fattest of the bunch, the National Park Service said in a press release. "Are you ready for #FatBearWeek , where Katmai’s beefiest bruins flaunt their fluffvying for glory as if they're the wobbliest, blue-ribbon-winning Jell-O mold at a Midwest state fair?" This year's bracket will be revealed on Monday at 7 p.m. ET
