At a meeting of the college faculty, an angel suddenly appears and tells the head of the philosophy department, "I will grant you whichever of three blessings you chose: Wisdom, Beauty - or ten million dollars."
Immediately, the professor chooses Wisdom.
There is a flash of lightning, and the professor appears transformed, but he just sits there, staring at the table. One of his colleagues whispers, "Say something."
The professor says, "I should have taken the money."
