Look closely ... it's an actual product that was really made and really sold and really used ... see what it is? Oh, c'mon. Look again. It's an arm-wrestling machine!!!
Now, have you seen the movie Philadelphia Story? There's a line - an answer to "it doesn't take much imagination to figure out what happened." The answer is, "not much, perhaps, but of a certain kind."
Well, how much of a certain kind of imagination does it take to anticipate the possibility that an arm-wrestling machine might not be a good idea? I figure the answer is somewhere between knowing the probabilities of success for a kid who says, "if I hold the sheet out just right, I will fly off this barn roof," and ... say ... being able to anticipate that one might burn food left too long on the stove. Not much, perhaps, but of a certain kind.
So what happened? They released this innovation into the marketplace, and lo and behold, people got their arms broken! Go figure! They're recalling it - and the manufacturer is quite certain that it must've been the fault of the players themselves that they got injured. I must say, I agree with the manufacturers. Players would not have needed much imagination ... but only of a certain kind.
