Another stupid inconsistency (or amusing quirk, if you like the show) was the IOU system: whenever Michael Knight had saved someone from financial ruin or some other horrible fate and was offered a reward, he'd decline and instead say that "you owe me a favor. One day, I'll come to collect it, and then you have to do it, no matter what it is". Now this may seem fine and dandy at first glance, but even if we ignore that this makes him sound like the villain in a fairy tale, it is also completely illogical, because in order to gain this IOU, he invariably used at least one, and frequently more, IOUs from other people he had presumably helped before. So how in hell is this system in which you continually use more of a resource than you acquire, supposed to work??
