Most of us enjoy stories about naïve amateurs who make bizarre mistakes. We chuckle knowingly over the man who complained about the performance of his new powerboat, only to have the marina staff discover that he’d launched the boat without taking it off the trailer, or the woman who mistook the CD-ROM drive on her computer for a retractable cup holder. Such tales permit us to feel savvy and urbane by comparison.
The Galilean fishermen, hard at work on their nets, may have recalled stories like that when the teacher from Nazareth asked to use one of their boats as a podium. A bit later they had proof of his ignorance when he told them to cast their nets in the deep during broad daylight. Perhaps then folks joked, “Those that can, do; those that can’t, teach.”
