The comedian John Oliver was quoted as saying, about an inflatable floating barbacue grill, which lets you cook while soaking in your pool:
"Is there any greater example of what it is to live in the freest nation on Earth than that?", he marvels with no small dose of irony
Sure, it's funny, just the idea of cooking in a pool. But why would it be ironic that freedom would produce strange outliers? In a free society, most people would be most like most other people. But out on the ends of the bell curve you've got some strange people doing strange things, and selling strange stuff. The face that you can find this strangeness is good evidence that America really is the freest nation on Earth.
