I'm sure we always partook of the swine. Lotsa mutton, too, and yes, eventually, poultry of all kinds.

Are you familiar with Terry Pratchet's Discworld series? If not (and for those readers of this thread who are not) "Discworld" is a paralell world -- and spoof -- of Earth (Britain), with magic and and overload of puns and wierdness.

Anyway, in this world, the "Father Christmas" figure is called "Hogfather," and his sleigh, like Freyr's chariot, is pulled by boars -- only by now, they are the overly-fat, snorting, domestic kind.

I am not overly familiar with the series, but a friend sent me a copy of the novel Hogfather for Christmas, a few years ago.
