I’m in a windowless classroom all day all week and the instructor is quite good at keeping us from drifting off. Every couple of minutes there’s a hand clap or a table slap report for punctuation. At first analysis I thought teach sounded like Fire Marshall Bill Burns with sentences beginning: “Lemme tell ya somethin’…” but now I’ve decided his voice is, if you can imagine it; Ned Flander’s (Simpsons) mixed up with drill sergeant, R. Lee Ermey (Mail Call).
