Apparently, even penguins are considered dangerous now that they have to pass through airport security machines. I can emphatize with Penny and Pat, who was described as the "more good looking one." I know I'm a little rusty, but how the hell do we know what an "attractive" penguin should be? More suave in his tux?
The ordeal made the penguins confused. I would be, too. I mean, a penguin as a threat to national security? Pat must be saying, "It's not like I planned to hijack the plane to Antarctica."
