The best thing I ate today -- actually am doing so right now -- is beer. Yes that's right: beer is "food". I never drink Bavaria, but beer's beer... it not only serves as a drink, but as food, for it would fill a person with-- what... two sandwiches? Therefore -> beer = multipurpose consumption product.

Especially if you buy a little crate of beer, it serves more than just to be consumed. The bottles can be used as light quick weapons close or afar; the crate itself can be used as a heavy (slow) weapon.

But wait(!), there's more. You can even use the beer crate as foot support to rest your tired legs and feet. Or you can use the crate to sit on outside if there's nothing else around. You can even use the bottles to juggle if you feel like it (and are good enough).

How's that for multipurpose use of a crate and bottles, besides the food/drink functions of the beer itself, eh? Brilliant
