My brother used to tape these on a tape recorder back in the 1970s and play them for me. He is that show's biggest fan, and knows every episode.
My favorites are "Talkie Tina", and "The Jeopardy Room", where the bomb was planted in the phone. I liked how the room was numbered 963. Reducing those individual numbers to their lowest common multiples, you get 321............BOOM!
Have a good one,
