found this interesting tidbit ... and I would place it on equal par with some of the "facts" offered in this thread so far...

The only CEO of the top-50, whose education is listed as n/a is Martin
J Sullivan, the CEO of AIG, and despite my best efforts, I couldn't
find where (or whether) he went to college. However, if he hasn't gone
to college (which I doubt, I think that his full biography is just
unavailable online) he is the only one of those top-50. I have checked
for the other 49, and they all *graduated* from college.

Hmmm .. AIG ... really now where have I heard that recently?
