We're not going to even try to dissect this one. Not even for a second. Straight from our favorite purveyors of the unsettlingly sexy and bizarre, a Japanese company called Kitan Club has unleashed panties for bottles...for some reason. These little suckers are 200 yen ($1.6) and fit comfortably on the bottom of your bottle, covering its most private of private parts.
We can't go as far as to say this improves the drinking experience, but we also can't disprove the opposite. Just buy them, see for yourself, and don't ask why...because you're just not going to find a satisfactory answer.
