Re: common::sense .... what???
"And every time I hear that song, my ear hurts."
an earworm is like a babelfish, except that it plays the damn song in your head and feeds off of your insanity [as opposed to doing what the babelfish does, which is like symbiosis]
which makes for a nice distraction-level side topic: an excellent exercise in mental discipline is to teach yourself how to shut off an earworm on demand. many positive benefits.
