"Pig"'s origins?

[LARSSON at VAX1.Mankato.MSUS.EDU]

I just yesterday picked up one of the Twin Cities weeklies, which
contained an article on an etymologist at the University of Minnesota
who is working on a new dictionary of word origins.  A picture and caption
suggested that the word "pig" is of obscure origin, and my micro-copy
of the OED confirms it: "Origin unknown."

Seems fitting.
