Here's a video of two penguins — Pete and Penny — chilling in first class on a flight from Atlanta to New York, where they were guests at the premiere of Discovery Channel's documentary Frozen Planet. I'm thinking there are two joke possibilities here: something about "flightless birds" and something about how of course penguins would be in first class; they're always wearing tuxedos. Mostly, though, I think all planes should have penguins. [via Yahoo]
