I'd first heard the mystery theatre as a 14 year old kid riding in the back of my parent's VW beetle to Illinois (episode: "The forever man") but after that didn't hear it at all until 4 years later when I caught the mid-second act of another episode and was hooked. Which episode? THIS one.

BTW, even though I didn't know the full story I had fun with it. My Mom was a high school drama teacher who had some great kids in her class. I remember telling them about this and in future conversations we'd say: "Could one of them have been...UNA?!?!"
