This immediately comes to mind: https://www.youtube.com/results?search_query=tom+waits+building+in+there.
“What the hell is he building in there?”
And yeah, I love that “Rhetoric involves a great deal of consideration for many factors.” It’s certainly important “to consider your audience, the occasion, your knowledge,” and I think you’re touching on something new (to me) by discussing “the persona [one] will be portraying.” I think I understand what you’re getting at — the constructed personality as a means to relate to an audience. As you asked, “Should I lower my vocabulary and talk like a your average 18 year old when giving a speech, or when much less is at stake, maybe in class?” It’s a valid question. Have you ever seen Thug Notes on YouTube? The dude is extremely intelligent, appeals to both low/high standards — low with his Rhetoric, high with his ideas — and gets the job done. https://www.youtube.com/results?search_query=thug+notes+
I think the tool metaphor seemed strongest in that last paragraph! “There are many times when the when you might bring the wrong tools to the job.” That’s pretty much every day for me.
