I love me a good arithmetic/algebra review -- but in the end, I am not qualified to rub elbows with the geniuses of Mensa, as I lack the essential requisite domain-specific kitten/mitten training.

References aside, I certifiably lack enough legit brains to step to Mensa's gatekeepers. But now I'm curious -- has anyone got any anecdotes of Mensa gatherings that defied stereotypes? Such as for example those alluded to in Mr. Onstad's synopsis of Mensa here: http://achewood.com/index.php?date=03222005
