When Michael Stipe was little, his parents called him Mr. Mouse. He was a scurrier. As soon as he could stand, he ran, and when he ran, he ran until he face-planted. His mother would deposit him in a baby walker, but if Stipe scrambled as fast as he could and hit the threshold of a doorway with a running start, he could topple the walker and eject himself onto the floor. Then he’d spring to his feet and run away.
