it was told in an interview with one of his instructors at Harvard. Bush went to Yale as an undergrad. The professor had an article in salon.com --
http://dir.salon.com/story/news/feature/2004/09/16/tsurumi/index.html...."I don't remember all the students in detail unless I'm prompted by something," Tsurumi said in a telephone interview Wednesday. "But I always remember two types of students. One is the very excellent student, the type as a professor you feel honored to be working with. Someone with strong social values, compassion and intellect -- the very rare person you never forget. And then you remember students like George Bush, those who are totally the opposite."
The future president was one of 85 first-year MBA students in Tsurumi's macroeconomic policies and international business class in the fall of 1973 and spring of 1974. Tsurumi was a visiting associate professor at Harvard Business School from January 1972 to August 1976; today, he is a professor of international business at Baruch College in New York.
Trading as usual on his father's connections, Bush entered Harvard in 1973 for a two-year program. He'd just come off what George H.W. Bush had once called his eldest son's "nomadic years" -- partying, drifting from job to job, working on political campaigns in Florida and Alabama and, most famously, apparently not showing up for duty in the Alabama National Guard.

Many of Tsurumi's students came from well-connected or wealthy families, but good manners prevented them from boasting about it, the professor said. But Bush seemed unabashed about the connections that had brought him to Harvard. "The other children of the rich and famous were at least well bred to the point of realizing universal values and standards of behavior," Tsurumi said. But Bush sometimes came late to class and often sat in the back row of the theater-like classroom, wearing a bomber jacket from the Texas Air National Guard and spitting chewing tobacco into a cup. (I've heard the professor talk, and he also said Bush threw spitballs, but it isn't in this article)
Tsurumi goes on to say he showed pathological lying habits. When challenged on something everyone heard him say, he'd deny saying it. Bush also said the government shouldn't help poor people because poor people are lazy. If students challenged him in class, he would start a whispering campaign against them, using innuendo and lies. He felt he was entitled to go into TANG and was cunning and vengeful. Scary but insightful reading. (paraphrasing so I can stay within the 4 paragraph rule)
