I was passing by a mosque and a sign asserted that the Quran is miraculous in that it is the only book that can be memorized. I have also heard this asserted by Moslems.
Now there are several short children's books that I have memorized and the 1.6 billion Moslems aren't going to abandon their faith just because I have memorized all 7 sentences of "Caveman Dave."
So what are the details of the challenge? It should go something like this: The Quran is the only book that is ______ long and _____ complicated that can be memorized.
