oddly, to wean cannibals from their lust for human flesh, researchers found that the cannibals found spam to be an adequate substitue.
ok ok ill 'can it,' but it just might be true...
Turning to Theroux's Happy Isles (1992), we find the following:
It was a theory of mine that former cannibals of Oceania now feasted on Spam because Spam came the nearest to approximating the porky taste of human flesh. ‘Long pig’ as they called a cooked human being in much of Melanesia. It was a fact that the people-eaters of the Pacific had all evolved, or perhaps degenerated, into Spam-eaters. And in the absence of Spam they settled for corned beef, which also had a corpsy flavor.
