(h/t Mark Shea)
Leprechauns (lupercorns) are tricksy and deceiving. Could this be why Loki always was trying to trick Thor? Was Loki a Lu(per)Co(rn)? Inquiring minds want to know.
Of course, we all know that this is simply a prefigure of the War in Heaven between Michael - an Irish name, right? - and Lucifer. And if we remember that the classical Latin c was pronounced always as k, there is some hidden relationship between Loki and Luci(fer).
See? It all makes sense.
