In 1975 I was twelve years old. I had my own TV in my bedroom and I secretly watched this episode. I remember it being very good and somewhat "taboo" for that time. I was intrigued by the plot and subject matter of this episode. As far as a kid in 1975 goes, this was something that I had never heard of. Sex change operations? Men becoming women? I remember sitting so close to my black and white television set so I could quickly change the channel in case my parents walked in my room and caught me watching such a thing. This was one of the very first shows that I can remember having the parental supervision warning before the show started. It was all a big deal back then.
