Wonderful idea.
Speech was my favourite college courses (yes I took two, and even gave my commencement address at age 45).
My late step-father encouraged me to get into speech in high school a long time ago.
Whatever you do, keep the audience entertained, because once you lose them you will play hell getting them back.
Start out with some amusing story (there should be plenty of fodder for that here), and if you can, conclude with a final reference to that opening story. I always called it "coming full circle", and it makes it memorable and impresses the prof.
I will anxiously await your stories about this project and would even be interested in reading a copy should you choose to make one available.
Good luck to you, and go make a positive impact about cigars!!
