Did you know these little bits of history?

In George Washington's days, there were no cameras. One's image was
 either sculpted or painted. Some paintings of George Washington showed
him standing behind a desk with one arm behind his back while others
showed both legs and both arms. Prices charged by painters were not
based on how many people were to be painted, but by how many limbs
 were to be painted. Arms and legs are 'limbs,' therefore painting them
would cost the buyer more. Hence the expression, 'Okay, but it'll cost
you an arm and a leg.' (Artists know hands and arms are more difficult
 to paint)

As incredible as it sounds, men and women took baths only twice a year
(May and October) Women kept their hair covered, while men shaved
their heads (because of lice and bugs) and wore wigs. Wealthy men
 could afford good wigs made from wool. They couldn't wash the wigs, so
to clean them they would carve out a loaf of bread, put the wig in the
shell, and bake it for 30 minutes. The heat would make the wig big and
 fluffy, hence the term 'big wig.' Today we often use the term 'here
comes the Big Wig' because someone appears to be or is powerful and
wealthy.

In the late 1700's, many houses consisted of a large room with only
 one chair. Commonly, a long wide board folded down from the wall, and
was used for dining. The 'head of the household' always sat in the
chair while everyone else ate sitting on the floor. Occasionally a
 guest, who was usually a man, would be invited to sit in this chair
during a meal. To sit in the chair meant you were important and in
charge. They called the one sitting in the chair the 'chair man.'
Today in business, we use the expression or title 'Chairman' or
 'Chairman of the Board..'

Personal hygiene left much room for improvement. As a result, many
women and men had developed acne scars by adulthood. The women would
spread bee's wax over their facial skin to smooth out their
 complexions. When they were speaking to each other, if a woman began
to stare at another woman's face she was told, 'mind your own bee's
wax.' Should the woman smile, the wax would crack, hence the term
 'crack a smile'. In addition, when they sat too close to the fire, the
wax would melt . . . Therefore, the expression 'losing face.'
*******
Ladies wore corsets, which would lace up in the front. A proper and
 dignified woman, as in 'straight laced'. . Wore a tightly tied lace.
*******
Common entertainment included playing cards. However, there was a tax
levied when purchasing playing cards but only applicable to the 'Ace
 of Spades.' To avoid paying the tax, people would purchase 51 cards
instead. Yet, since most games require 52 cards, these people were
thought to be stupid or dumb because they weren't 'playing with a full
 deck.'
*******
Early politicians required feedback from the public to determine what
the people considered important. Since there were no telephones, TV's
or radios, the politicians sent their assistants to local taverns,
 pubs, and bars. They were told to 'go sip some ale' and listen to
people's conversations and political concerns.. Many assistants were
dispatched at different times. 'You go sip here' and 'You go sip
 there.' The two words 'go sip' were eventually combined when referring
to the local opinion and, thus we have the term 'gossip.'
*******
At local taverns, pubs, and bars, people drank from pint and
 quart-sized containers. A bar maid's job was to keep an eye on the
customers and keep the drinks coming. She had to pay close attention
and remember who was drinking in 'pints' and who was drinking in
 'quarts,' hence the term minding your 'P's and 'Q's

One more and betting you didn't know this!
In the heyday of sailing ships, all war ships and many freighters
carried iron cannons. Those cannons fired round iron cannon balls. It
 was necessary to keep a good supply near the cannon. However, how to
prevent them from rolling about the deck? The best storage method
devised was a square-based pyramid with one ball on top, resting on
four resting on nine, which rested on sixteen. Thus, a supply of 30
 cannon balls could be stacked in a small area right next to the
cannon. There was only one problem...how to prevent the bottom layer
from sliding or rolling from under the others. The solution was a
metal plate called a 'Monkey' with 16 round indentations.
However, if this plate were made of iron, the iron balls would quickly
rust to it. The solution to the rusting problem was to make 'Brass
Monkeys.' Few landlubbers realize that brass contracts much more and
 much faster than iron when chilled.
Consequently, when the temperature dropped too far, the brass
indentations would shrink so much that the iron cannonballs would come
right off the monkey. Thus, it was quite literally, 'Cold enough to
 freeze the balls off a brass monkey.' (All this time, you thought that
was an improper expression, didn't you.)
