There are some chuckles in there, too. I listened to the whole thing, and didn't think for a second that anybody was being serious. After departure, when they were talking to Tower instead of Departure (hadn't flipped over), they used funny accents to do that, too. I thought the "rant" accent was soooo over-the-top Texan it sounded like a character on King of the Hill. I thought they were just having some fun, like Steven Colbert's former-show conservative character, etc., with their over-the-top references to burning coal and driving too slow and Hyundais. If you view it as satire, it's not hilarious comedy but not awful for a couple of amateurs.

The Thought Police disagree, however. I mentioned my views in a thread elsewhere and was promptly roasted from every corner about how the pilot was clearly-serious and it was unprofessional and it was "illegal" because it violated sterile cockpit and on and on. Oy. I got in my coalburner and roared out of there at high-speed past the Hyundais, y'all.
