From my friend Dr. Rich Klimoski, a Business School Dean:
A dean was meeting with a group of faculty when a genie appeared. The genie offered the dean either great wisdom or great wealth. The dean immediately asked for great wisdom. The genie said “Your wish is granted” and then vanished in a puff of smoke.
The faculty members gathered around the dean in anticipation, asking him “Now that you are so wise, what do you know?”.
The dean sighed and said “I know that I should’ve taken the money”.
