Did you say 'drawer' or 'door' cause I thought you said 'door'.
When Andy has to deliver Sam the farmer's new son, Barney keeps Sam occupied with at least 17 Army stories. He begins with "I did my part to beat the dreaded hun." How many people would know what that meant ? The writers put things like that in often that I think only they and a small no. in the audience would have any clue as to what they meant. Why did they do that ?
I think phrases like that were very well known at the time but the producers and writers had no idea that America would be watching reruns over sixty years later and after the phrase had long been discarded by society. I catch a lot of instances of accepted idioms that have gone by the wayside.
If you were to read up on General Patton, you would know the term "hun"! But not too many are doing that these days.
I wonder where the other 5300 people of Mayberry were hiding. The population is reported to be 5360. The most I had seen were greeting the gold truck and also the ones at the train station to meet Teena Andrews. Maybe 60 at the most.
