Let's step back for a second and begin at the beginning. Going out in public, it turns out, is a different thing than staying at home in private. In private you're all alone, but public there are other people. What you do in public affects those other people, and so societies have to develop rules to prevent any single person from spoiling things for everybody else. Those rules may involve behavior or hygiene or fashion, but the critical point is that when you violate them people point at you and laugh. That way you know you've erred. Because "not caring what other people think," far from being a virtue like they taught you in kindergarten, is actually a diagnosable clinical condition.
Now at some point travel gear producers forgot about our society's rules. They started telling people that it was OK to walk around with pool floaties on their arms or in shoes made out of foam, as if airports and bus stations aren't public venues. They created the SkyMall catalog because apparently when you sit in an airplane seat you become invisible and can wear or do anything you want. Which brings us back to the SnazzyNapper, which is a blanket that you more or less bolt to your head.
We're not going to get into too many details, partly because you can see the commericial for yourself below and partly because it really does make us kind of sad. And no, it's not a joke. Here's the official site, here's the CNN story, and here's the Twitter feed. The most recent tweet, as of publication? "Have a Snazzy Day! :)" A smiley and an exclamation point. Honestly, there are not enough middle fingers in all the world.
