I is well proper clever cuz I knew all of these apart from the posh thing :smilewinkgrin:
What about "upper crust"? This came from when bread was made for huge dinning parties, the bottom of the loaf would burn so the loaf would be cut in half sideways (to cut the bottom off). The richguestss would eat the top of the loaf and the black bottom of the loaf was given to theservantss. Hence "upper crust"
Then "giving the cold shoulder". This is from when woman used to cook a shoulder of lamb for the husband when he was out hunting. If the man was late because he had been out with the boys, the wife would not keep the shoulder warm but give him the cold shoulder.
The word "plumber" is meant to come from the roman word from lead but i could well be wrong about that one.
To "show your metal"? This came from the guys in the old days that used to use a huge mill for grinding grain to make bread, when the mill needed fixing or maintaining, there would be peoplequeuingg up for the work as money was alway tight. But it was veryimportantt to get someone that knew what they were doing. In the process of fixing these mills, the workmen would get lots of metal splinters in their forearms, so to see how muchexperiencee the guy had he was asked to how muchmetall he had in his arms "show your metal".
