If you haven't heard of the body modification called "bagel head", you're in for a treat.

Apparently tattoos and piercings are too boring for some people, so they get saline injections in their FOREHEADS, until it looks like there's a BAGEL under their skin.

The National Geographic Channel show "Taboo" did a segment on it, and part of it's on YouTube.  Eventually the saline absorbs into your body, so it only lasts about 16 hours.  Meaning, it just TEMPORARILY makes you look like a lunatic.
