I think the first thing that I did…

FZ: "I think the first thing that I did that gave me a clue that I had a career as an entertainer was when I had to give a lecture in a science class about ferns and got a lot of laughs. Course I wasn't trying to be funny. It was a nice experience and all I had to do was talk about ferns and deliver the facts in my own way and people laughed and that was good. I went on from there."
