BotP episodes

For those of us that watched BotP in the late 70's, like me. Can you remember what episode you saw first? Which episode do you remember the best?

For me I thinking it was "The Space Mummy"
The one I remember the best was "The Fierce Flowers"

 

I can't remember which one I saw first, but the one I remembered best would have been "The Fierce Flowers" - in fact for about 20 years, that episode stayed seared in my memories.

Having watched all of them again many times now, my all time favorite episode, thought, is "The Conway Tape Tap", followed by "THe Fierce Flowers"
