During a heat wave, it's easy for sluggishness to set in. Even the quickest, simplest task feels like drudgery. During those times, "Heigh Ho" sometimes runs through my mind--the grim Tom Waits rendition, though, not the happier "Snow White And The Seven Dwarfs" version. When just getting from a building to one's car feels like a joyless, mine-digging ordeal, I appreciate what Waits did with "Heigh Ho" all the more.
