Pack of canned goods

Mammoth steaks are great in theory, but in practice, you're better off with something tangible: a good old-fashioned pack of canned goods . They're puncture-proof, shock-resistant, and have a shelf life longer than a city dweller stranded in the wilderness. With them, you don't have to hunt, fish, or beg a squirrel to share its loot.

What if the apocalypse really doesn't come? No problem, these wonders can be recycled into bird feeders , flower pots, or homemade grenades (but that's another story).
