Every few months, some yahoo on YouTube posts a video of themselves eating corn on the cob which has been stuck on a power drill—allowing them to eat it in just a few seconds.

Like all successful videos, these inevitably spark copycats. Besides the fact that it looks like you could easily knock your teeth out, there's another risk that comes into play when your hair is longer than the buzz cut that young man has in the 2012 video. This week, some poor woman in Asia (perhaps a viewer can comment as to what language she's speaking in the follow-up video) demonstrated the danger of this video for the whole world's education.
She posted a follow-up in the doctor's office. Fortunately, she merely removed her hair and not her scalp. This could have been much worse.
