The need to fear pigs, and their keepers, is well documented in recent films. Hannibal springs to mind, but I like this quote from Snatch:
"You need at least sixteen pigs to finish the job in one sitting, so be wary of any man who keeps a pig farm. They will go through a body that weighs 200 pounds in about eight minutes. That means that a single pig can consume two pounds of uncooked flesh every minute. Hence the expression, "as greedy as a pig.""
