I’m binge-watching the second season of Brooklyn Nine - Nine these days. Will you believe they had the old “character who has never been seen near a cigarette suddenly happens to be a long time smoker quitting for that episode”? And no, not even in an ironic meta way, like they did in HIMYM, no. They did it for real.
It’s not even the fact that I thought that cliché had been buried since the early nineties, it’s that it happened in the TV show I least expected to see it sprung, since otherwise it’s written in a fairly self-aware way.
