In the good old days, you gave someone a watch as a gift. Now you give them a watch as a combination of "gift" and "unremitting drill sergeant who lives on your arm and shouts at you when you've been sitting on the couch eating Cheetos and watching Shark Tank reruns for too long". But the good news is, you can save $50 on various kinds of drill sergeants at Crutchfield.
