Its the stuff other folks say about this guy that is funny.
"Unlike most savants, he shows no obvious mental disability..."
Normal brains just can't help but get all nasty about it.
They're like those short guys that always go around getting into trouble with tall people.
I have to admit, even with my superhumanly humongous and fantastically awesome Super Brain, the first thing I thought was "Yah, but what has he done for me lately?" and "Math? Pfft. That's a crappy super power! Does he know any Super Jokes? Bah! Booorrriiinnng!"
