"Come back, Zinc...come baaaack!"
Jeremy Lott has a post explaining that he is taking zinc to ward off a cold. In a response that he doesn't quote on his own weblog, Kevin Steel suspects that he is playing into an elaborate alien overlord scheme.
My observations would be more plebian. Zinc now reminds me of that educational film about zinc in The Simpsons. A teenager gives up using zinc and finds that his phone won't work, the car won't start. He's reduced to crying plaintively, "Come back, zinc, come back!"
I can deal with alien overlord schemes as long as I have my phone!
