Leprechauns may wear green on St. Patrick's Day, but there's good reason for them to be blue: Irish folklore suggests there aren't any females.
An ancient book called "A History Of Irish Fairies" reveals that there are no evidence of there being a female leprechaun -- ever.
It gets worse: Some leprechaun experts speculate that the wee creatures are the offspring of fairies who were deemed "defective children...because of their shape and disposition," TheFW.com reported.
No word on how leprechauns reproduce either, but apparently they do, because an area called "The Sliabh Foy Loop" near the town of Carlingford is apparently home to 236 of them, and they are protected under European law, according to Irish Central.com.
