Gentoo penguins in Antarctica

For the uninitiated, the origins of the made-up holiday Festivus can be traced back to an episode of the hit '90s show, 'Seinfeld.' Based on the real family tradition of one of the show's writers, Festivus has taken on a life of its own in the real world and provides fans with a fun, tongue-in-cheek way to celebrate the holiday season while ignoring its pressures and commercialism.

And with today's photo, it appears these Gentoo penguins in Antarctica are well aware of Festivus, as one seems to be engaging in one of the holiday's main traditions—the 'Airing of Grievances.' And as far as Gentoos go, it's not uncommon for them to have plenty of grievances to air. Whether over excommunication for infidelity, or jealousy over their neighbor's nesting stones, Gentoos can be salty. Maybe that's to be expected, though, as their diets are so loaded with the stuff that they literally leak highly concentrated saline from their beaks.
