A lock of hair from an Austro-Hungarian emperor who ruled in Europe more than a century ago fetched about $18,000 at auction in Vienna yesterday—about 20 times the estimated price, reports the AP. An Austrian restaurateur bought the white lock once belonging to Franz Josef, whose reign from 1848 to 1916 made him one of Europe's longest-serving monarchs, reports the BBC. It's an impressive price, but the BBC also notes that Justin Bieber's hair sold for charity on eBay in 2011 for about $38,000. (More strange stuff stories.)
