In one fell swoop, David Letterman killed disco. Not just the music, but the entire polyester empire of rhinestone smarm and sweat-drenched earnestness. Letterman wasn’t seduced by mirror balls. He walked on stage with his arctic deadpan, and with irony as his weapon, executed disco in front of a live studio audience.
I was just starting college then—a lifelong bodybuilder and Olympic weightlifter who could hoist a barbell but couldn’t hoist a personality. Muscles, yes. Presence, no.
I didn’t just want to be David Letterman. I wanted to graft his sardonic detachment onto the icy brilliance of Vladimir Nabokov—a cocktail of late-night sarcasm and literary menace. I didn’t know what I wanted to be, exactly, only that it had to involve confidence, storytelling, performance—something that allowed me to “give a presentation.”
By accident, I stumbled into teaching. In 1987, the chancellor of Humanities at Merritt College launched a pilot program to deliver classes at Skyline High School in Oakland, and none of the full-time faculty wanted the job. My neighbor, Felix Elizalde, whose kids went to school with me, threw me a lifeline. One gig snowballed into another, and soon I was a full-time college writing instructor.
That was thirty-eight years ago. For most of them, I would have told you the hardest part of the job was grading essays—an endless swamp of half-baked theses and misplaced commas. But now, in 2025, grading essays is only the second hardest task. The first? Something educators and administrators alike love to call “student engagement.”
I don’t know if it’s the black hole of smartphones or the simple math of age—I’m nearly forty-five years older than my students. Probably both. Either way, I can no longer stand in front of a classroom, channel my inner Letterman, and spin stories until the room vibrates with attention. Instead, I stand beside a giant screen plastered with Google Slides. My students are “visual learners,” raised on swipes and emojis.
I could go back to the Letterman Method, earn some laughs, maybe even spike engagement for a few minutes. But at what cost? The Google Slides aren’t as funny as my comedy routine, but they do hit the sacred “core concepts” and “Student Learning Outcomes.”
I’ve become a ghost haunting the pedagogy manuals. Occasionally I slip, crack a joke, earn some chuckles, channel my younger self—but then I reel myself back in, because the templates for counterarguments and rebuttals won’t teach themselves.
The students aren’t fooled. A few of the candid ones smirk: “Don’t worry, McMahon, ChatGPT will do it for us.”
And so, as I enter my mid-sixties, I keep trying to stay aligned with the modern world. Yet every step forward feels like five steps backward, as if I’m not teaching writing anymore but rehearsing my own obsolescence.
