Golems
 
In mediæval times, before much of the ancient knowledge of alchemy and natural science was lost, a few skilled scientists were able to construct living creatures from inanimate substances by chemically combining very large molecules in such a manner that their shemps actually increased.

The Golem was made by forming the shape of a man in pure distilled mud, adding carefully calculated amounts of trace elements (mostly salt and biscuits, but the exact formula has been lost), and finally impressing the hebrew symbol יה meaning "life" into its forhead with the thumb. The most skilled alchemists were able to produce a creature of the fourth shemp; virtually indestructible and unquestioningly willing to do their bidding, and one was once created with the power of speech. The creature ultimately turned on its creator and killed him by pushing a pencil up his nose as far as it would go, and retired to the country where it became a small but malevolent flower bed, and eventually lost consciousness after a heavy rain smudged its forehead.

The Geneva convention specifically prohibits research directed towards the rediscovery of the alchemical formulæ for Golem construction.
