A Little History

Piss poor
They used to use urine to tan animal skins, so families used to all pee in a pot & then once a day it was taken & sold to the tannery, if you had to do this to survive you were "Piss Poor",

Don't have a pot to piss in
But worse than that were the really poor folk who couldn't even afford to buy a pot......they "didn't have a pot to piss in" & were the lowest of the low.

Bride's Bouquet
Most people got married in June because they took their yearly bath in May, and they still smelled pretty good by June. However, since they were starting to smell.  Brides carried a bouquet of flowers to hide the body odor: hence, the custom today of carrying a bouquet when getting married. 
     
Dont' throw the baby out with the bath water
Baths consisted of a big tub filled with hot water. The man of the
house had the privilege of the nice clean water, then all the other sons and men, then the women and finally the children. Last of all the came the babies. By then the water was so dirty you could actually lose someone in it. Hence the saying, "Don't throw the baby out with the Bath water!"

Raining cats and dogs
Houses had thatched roofs-thick straw-piled high, with no wood
underneath. It was the only place for animals to get warm, so all the cats and other small animals (mice, bugs) lived in the roof. When it rained it became slippery and sometimes the animals would slip and fall off the roof.  Hence the saying "It's raining cats and dogs."

Canopy beds
There was nothing to stop things from falling into the house. This posed a real problem in the bedroom where bugs and other droppings could mess up your nice clean bed. Hence, a bed with big posts and a sheet hung over the top afforded some protection. That's how canopy beds came into existence.  

Dirt Poor
The floor was dirt. Only the wealthy had something other than dirt;
hence the saying, "Dirt poor."

Thresh hold
The wealthy had slate floors that would get slippery in the winter when wet, so they spread thresh (straw) on floor to help keep their footing. As the winter wore on, they added more thresh until, when you opened the door, it would all start slipping outside. A piece of wood was placed in the entrance-way;   hence: a thresh hold.

Peas Porridge
In those old days, they cooked in the kitchen with a big kettle that always hung over the fire.. Everyday they lit the fire and added things to the pot. They ate mostly vegetables and did not get much meat. They would eat the stew for dinner, leaving leftovers in the pot to get cold overnight and then start over the next day. Sometimes stew had food in it that had been there for quite a while. Hence the rhyme: Peas porridge hot, peas porridge cold,peas porridge in the pot nine days old.

Bring home the bacon, Chew the Fat
Sometimes they could obtain pork, which made them feel quite special. When visitors came over, they would hang up their bacon to show off. It was a sign of wealth that a man could, "bring home the bacon." They would cut off a little to share with guests and would all sit around
and "chew the fat".

Poisonous tomatoes
Those with money had plates made of pewter.Food with high acid content caused some of the lead to leach onto the food, causing lead poisoning death. This happened most often with tomatoes, so for the next 400 years or so, tomatoes were considered poisonous.

Upper Crust
Bread was divided according to status. Workers got the burnt bottom of the loaf, the family got the middle, and guests got the top, or the "upper crust".

The Wake
Lead cups were used to drink ale or whiskey. he combination would sometimes knock the imbibers out for a couple of days. Someone walking along the road would take them for dead and prepare them for burial. They were laid out on the kitchen table for a couple of days and the family would gather around and eat and drink and wait and see if they would wake up; hence the custom of holding a wake.

Graveyard Shift, Dead Ringer 
England is old and not much land so the local folks started running out of places to bury people. So they would dig up coffins and would take the bones to a bone-house, and reuse the grave. When reopening these coffins, 1 out of 25 coffins were found to have scratch marks on the inside and they realized they had been burying people alive. So they would tie a string on the wrist of the corpse, lead it through the coffin and up through the ground and tie it to a bell. Someone would have to sit out in the graveyard all night (the graveyard shift.) to listen for the bell; thus, someone could be, saved by the bell or was considered a dead ringer.
