I got a sneak peek of the movie ‘Bad Teacher’ the other day, and was thoroughly impressed. I went to the screening with my good friend Jeanie, who happens to be a nurse in the Bay Area, and she told me there are some people on her hospital staff that remind her of Ms. Halsey from the movie. In the process of the conversation she mentioned a fake stethoscope that actually functions as a pair of head phones. I was so fascinated by this, I did a little digging and I found them. “Stetheadphones” allow you to make and receive calls, access voice-control features, and manage music playback from your iPhone or iPod. Quite ingenious.
