... is by far the most enjoyable thing ever after a triple-pass, DE shave. A freshly shorn upper lip is the single most sensitive instrument on the planet. The Sudbury neutrino detector, anti-theft lasers at the Louvre, seismographs, furuncles & carbuncles, the emotions of tweenager dressed in black.... nothing is more sensitive than a fresh upper lip. My cat's head pegs out at solid 10 on the upper lip scale-of-soft, too, and there are no simpler joys.
