You know what's better than a penguin on a plane? Two penguins on a plane! Even better than that: five penguins on three different planes (two of whom may possibly be the same penguin). Watch and learn.

Here's two adorable dudes waddling around the aisle on a flight from Orlando to New York. They seem so into it!

It is probably good that I am not these penguins' trainer because I would just be trying to get them to carry little briefcases all the time. Briefcases full of fish.
