Back in the Cretaceous, a casual reference to a microphone was rendered on the page as "mike." Nowadays, when I drive past the Champagne Palace, the sign says "Open Mic", and there's just no way that I can avoid pronouncing that as "mick". When did "mic" slip in when I wasn't looking, and is it odd to anyone else? Particularly after the once-near-ubiquity of Bic pens? Is a bicycle now a bic?
