Cutest video you'll see all day of penguins flying on a plane

[Video Link.] Yahoo's "Sideshow" blog has the story behind this video, and an accompanying photo gallery slideshow. On a recent Delta Flight, there were 300 or so human passengers and two foot-and-a-half tall penguins, Pete and Penny, who are 6 and 12 years old respectively. They were on their way to the New York premiere of "Frozen Planet," a new Discovery Channel documentary series narrated by Alec Baldwin. Like the narrator, the penguins fly first class. I hope they behaved better on the plane than he has been known to.
