I came across several variations on the image below. It is certainly an apocryphal story, but one that may perhaps be worth commenting on.
But what could one say about the story if it were true? On the one hand, to hand in five mostly or entirely blank pages knowing full well that one could fail, and that one would be less likely to fail if one filled the pages with relevant writing, certainly is a courageous act.
Finally, I imagine that real-life professors would hesitate to give an A+ even if they thought this was a genuinely creative and insightful answer, because other students might then try the same, appealing to this precedent. But that need not be a concern. The appropriate action would be to give them lower if not indeed failing grades, and point out that it is not courage to follow where someone else has successfully gone, merely in the hope of replicating their outcome and sharing in their glory.
As an aside, in relation to the quest for the historical Jesus, it is worth pointing out that this is one reason why multiple attestation alone is not a sufficient grounds for asserting that something is historical. There are certain kinds of stories that people love to pass on, and skepticism is thus called for among historians, as also among university applicants and college students
