To freeze the balls off a brass monkey has an interesting history too, many claim authorship from many military conflicts.
Essentially cast iron canonballs were stacked on a brass plate with indentations, this was called a monkey, on freezing cold nights the contraction rate of brass was much faster than the canonballs and they would noisely dislodge and fall off.
