Useless trivia:
BRASS MONKEY
In the middle ages, ships were heavily laden with food, water and cargo. Obviously, it was all stowed below decks. However, to be sure that the loading was even and didn't cause the ship to list to one side, an "n" shaped set of brass balls were hung from a spike on the deck, through two holes in the deck floor, so that they could be seen below. This created a kind of artificial horizon for the men below; if the balls shifted one way then they could tell they were causing the ship to list.
However, when it got very cold the wood in the deck would contract and snap off the balls. Hence the expression, "cold enough to freeze the balls off a brass monkey."
