Cough up that mucus!

In "Hocus Pocus Mucus Pucus", Walt accused marketers for Benylin and Buckley's of not knowing the difference between "mucous" (adjective) and "mucus" (noun). Just part of Walt's ongoing rant about proper English usage.
Well, it turns out that the folks at Benylin -- or their advertising agency, perhaps -- either do know the difference or are trying to have it both ways. Only yesterday, Walt saw a Benylin commercial, for "Mucus and Phlegm Relief". If I were going to buy an expectorant -- that's what it is -- I'd buy Benylin if only to support correct spelling.

The Benylin ad, by the way, is not as emetic as the Buckley's ad. Here we see only a woman coughing up a loogie into ... errr ... the inside of her elbow. Apparently that's the way you're supposed to do it now. Enjoy your lunch.
