Operation Welcome Mat

I stood on the bristly welcome mat by the front door, psyching myself up to breach the outside world, when I spotted a crisis in progress. A tall green plastic shoehorn was balanced precariously against a heavy boot, poised to crush an innocent dropped penny! I frantically flicked my fingers into maximum overdrive, roared, 'Halt, plastic crane of doom!' and charged forward into a heroic slide. Naturally, my toes caught the thick rubber border. I tumbled into an epic floppy spin, belly-flopping across the bristles and accidentally smacking the shoehorn flat with my hip. The penny bounced safely under the boot rim. Sprawled face-down with twitching hands, I mentally marked down another spotless victory.
