Let's be honest. Penguins are pretty much the coolest arctic bird out there.

Not only have they managed to successfully embrace gay marriage before their human counterparts, but they can also sing Christmas carols.

The San Francisco Zoo recently released a video of its adorable crop of Magellanic penguins squawking "Jingle Bells" in unison, and it's pretty darn heartwarming. We dare you not to crack a smile.

If the video isn't enough to fill your fix of seasonal animal joy, stop by the zoo from December 22 through the end of the month for its first-ever holiday light spectacle. You might even be able to get the penguins to sing a reprise (but probably not).
