Once in college, I was meeting with my advisor, who was also the department head. He had all my school records, including my test scores.  He said something about me qualifying to join Mensa if I wanted, and I said something about not liking Mensa since everyone I'd met who had been in the organization seemed arrogant.<p>It was only later that I realized he must have been in Mensa himself and was recruiting me.<p>Proving I wasn't nearly as smart as my test scores indicated.
