I'm fond of the old Dragnet radio shows. My local (USA) public radio station airs old radio on Sunday evenings, and Dragnet is on from 7:30 to 8:00. I like them so much, that when I saw a complete collection available on Audible.com, I snapped them up. I was taking a walk yesterday at lunch, listening to Dragnet on my iPod. At a certain point in the show, Friday and his partner interview a woman who operates a "French Laundry" in Los Angeles. It took a little Googling to find what a French Laundry is. Most of the hits returned by Google were reviews of a restaurant with that name. One or two involved sex acts. I was pretty sure that Friday and Romero weren't investigating that! Eventually, I learned that a French Laundry service provides specialized services in cleaning and pressing unusual or delicate clothing. Now these shows were written and presented from the late 1940's though the mid-1950's. I was born in the mid-1950's, and though I have a good memory for words, and I had heard the term before, I had no idea what it meant. How about some other terms which have vanished from common use in the past 60 years that were once so common that you could use them in a radio script with the assumption that all the listeners would understand them?
