Being in Professor Perley's class on the vapor capacity of air (in Meteorology 101) was not at all taxing because this much-loved pleonast, tender-hearted to the point of seeming maudlin much of the time, had such a low opinion of the intelligence of undergraduates that he said everything at least half a dozen times to give them a fighting chance of keeping up, and was at this moment warbling one of his famous strings of synonyms ("ice fog, frost fog, frost flake, pogonip, rime fog, air hoar. . .") which unfortunately, like elevator music, mostly served as ear candy, a soothing background noise for the students busy texting each other (except for a couple who later swore they heard him say "air whore" and later became meteorologists in the hope of tracking down this elusive phenomenon).
