Alex Martin a 3 year old from Arizona just became their youngest Mensa memeber after she memorized geography, and taught herself Spanish. Her parents first realized the smarts this little girl had when she began to recite her bedtime stories word for word (I cant even remeber what I ate for breakfast). Then as if that wasn't enough she has also memorized EVERY state capital, and taught herself Spanish on her parents iPad.
Finally to wrap up all this little girls awesomeness she scored so well on her IQ tests that the docs have not been able to calculate her true score! Though they estimate that it's around the same score as Albert Einstein, and Stephen Hawking.
