This is a USB-powered personal fan that hooks onto your necktie - you know, in case you were looking to stay cool and not get laid this summer.
The 28g Tie USB Cooler is sold by Japanese accessory maker, Thanko. It clips to the backside of your tie and is designed to push a steady stream of air through the button gaps of your shirt. Just plug it into any available USB port for power, or use the included battery pack to stay frosty (and un-sexed) while mobile. Unfortunately, it's only available in Japan and retails for about $US35. [Thanko via The Washington Post]
