Keeping with the amusement park theme from yesterday (variations on a theme park?), most of yesterday was devoted to a real life version of whack-a-mole. Whack-a-mole is a game wherein you have a mallet, and you stand facing some 'ground' with a bunch of holes in it. Each hole contains a mechanical mole, and they pop up at random intervals. Your job is to hit each mole on the head as quickly as possible when it pops up. It's remarkably satisfying.The real life version is satisfying, too, when it works. At least for a little while.
