For those puzzled by the joke, "long pork" is a euphemism for human flesh. Many south seas islanders were reputed to be cannibals, and enjoyed "long pork". The story goes that the only thing that would persuade them to abolish the practise was something that tasted just as good -- actual pork. Ham is still very popular in Polynesia, Hawaii, and other Pacific islands. But with no refrigeration, the only way to get ham for a long time was to keep live pigs. Obviously one cannot have ham every day, then. That all changed around WWII when US soldiers introduced a canned meat product from Austin, Minnesota: Spam. It's processed spiced ham, and although refrigeration is now readily available on many of those islands (but not all of them), Spam remains extremely popular.<br /><br />Whether or not this really has anything to do with "long pork" is a matter of some historical debate, since many of the early accounts of these islands were made by people who had something to gain by painting the natives as savages. Still, there is at least some truth to the headhunter tales. It's just hard to know where fact ends and fiction begins. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
