Sometimes when stuck with family around the holidays, it might be tempting to give them an earful, like this chinstrap penguin is doing here on the South Sandwich Islands. If that sounds appealing, or if you want a break from mandatory seasonal joy, Festivus might be the holiday for you. The secular holiday was popularised in a 'Seinfeld' episode in the show's final season. The Costanza family has a collection of odd traditions, including putting up an aluminum Festivus pole—for its high weight-to-strength ratio—and airing their year-end personal grievances. Since the episode debuted, the holiday has taken on a life of its own both among fans and people looking for an alternative way to celebrate the season. Those who love Christmas, Hannukah and Kwanzaa are welcome to them, and Festivus is for the rest of us.
