My wife swears I'm Japanese due to my insentient love of all things Japanese. But seriously they come up with the coolist must ridiculously useful stuff. I give you exhibit A :
This device sports a camera/light at one end and a viewer at the other end -- allowing users to see built-up ear wax. It's powered by a single 9V battery and is made from anti-bacterial ASB resin/glass/stainless steel.
Ok now I realize you have to do the whole "eeew" thing, but if you where home alone and this was in your bathroom, tell me you wouldn't use it!!
(it's ok I would too)
