I guess the whole conservation of matter thing was wrong after all.
You're gonna have a problem feeding 2.5 people from a 2 serving can. Apparently the best thing to best thing to do is divide the fish into 6 bags and pile it all together.
And when you got your six bags, you gotta transport them, because it's no good leaving in the deep freeze for your friends to smell, now is it? Then I hear the best thing to do is can them in a factory. You have get the factory up and running for a bit, then the site of a bag of fish will look like curry to a pisshead. You gotta cut the heads off your fish, and pull the guts out for the sake of the factory's machines. You could do this afterwards, of course, but you don't want to go sievin' through factory parts, now do you? They will can fish like a knife goes butter. You need at least 16 machines to finish the job in one sitting, so be wary of canners looking for fish. That means a single factory can process 2.5 servings per 2 serving can every minute. Hence the expression, "packed like sardines".
