I was just recently reminded of this episode: During Hodgepodge Lodge one year (I think it was the year ACT was around), the theme for the main get-together was labyrinths and maze. So I wrote (with some help from Michele) a lecture for Hodgepodge Lodge on mazes. To set the mood, I started parodying a commercial. I had obtained an ear of corn from a local market, and said, in an imitation of the tone of the woman in the commercial, "This is Maize. My ancestors knew it as... corn." I then looked at my notes, shook my head, tossed the ear of corn over my shoulder, and said, "Sorry, wrong lecture." The laughter was so hard that I looked over my shoulder, quite convinced that I must have hit John Algeo or Joy Mills in the face with the ear.
I still can't quite figure out why the audience found it more than mildly amusing...
