The Bluetooth cell phone headset has become so ubiquitous, that I no longer think "schizoprenic" when i see someone walking down the street talking to themselves. But this one would give me pause.  Even funnier than the retro cell phone headset I wrote about earlier, this one is wireless.  Imagine walking down the street, or pulling this out of your briefcase at a meeting.  $39.99 at ThinkGeek.com.
