Here we speak the mantra of "No Rugs, No Plugs, No Drugs."
Today, at a faculty meeting, I noted on an adjunct (horseshoe head; goatee) a sprinkling of sprouts on the rear of the bare dome, feeble little sprigs, and said to myself, "That person is getting transplants." A casual look at the chap's back-head clearly showed the source of the hopeful hair. I also said to myself, "What WAS he thinking of? It's not going to a damned thing good for him."
But I would never say anything aloud of this sort to anyone who is putting hope over experience. I hope that the Sly here would never confront anyone with plugs, but I'm sure we all roll our eyes when out of sight of the ... deluded fools, I guess I'd have to say.
