Guy a year above me got BS econ, BS math, MS statistics, MS computer science and PhD in business in 6 years at Stanford. He had to petition to take classes for fewer units as he was exceeding the quarterly limit.

Super nice, never had to study, always having a great time chilling in the lounge during finals. He's a professor at Cal->UPenn now.

I remember working with my friend on a math problem for an hour then I knocked on his door and he smiled and answered the question before I finished telling him the problem.

Kind of reminds me of the story Jeff Bezos tells of his friend Yasantha Rajakarunanayake who made him realize he was never going to be smart enough to be a physicist.
