Getting Good Vibes From This Student

(We’re graduate vocal performance students studying for our oral exams — basically, instead of a thesis on an academic topic, we assemble a committee of faculty members who ask us questions for an hour and a half about anything we might have learned in undergrad and grad school. We are working on pedagogy and it has been several hours by this point. I forget what the preceding question was, something about phonation.)

Friend #1: “Can you give an example of a vibrating object?”

Friend #2: “Sure, a vibrator.”

Friend #1: *with great pride* “Uh, yes, very good. A vibrator does make sound!”
