As brother Jeb says, "He truly enjoys getting people to knuckle under."

George W. Bush's belief in a "show of strength" may be further illuminated in another anecdote, again provided by Ron Suskind, this time in his The One Percent Doctrine (p. 215). A classmate of Bush's at Harvard Business School tells of playing basketball as captain of a team that played against another intramural team of which Bush was captain: "The game was tight. The other team's captain, Gary Engle... went up for a shot. Bush slugged him--an elbow to the mouth, knocking him to the parquet. 'What the hell are you doing?' Engle remembers saying.... Bush just smiled. Moments later, at the other end of the court, Engle went up for a rebound and felt someone chop his legs out from under him. Bush again." Later in his business career Engle ran into Jeb Bush in Florida and told him the story. "Jeb kind of laughed, Engle recalled. 'In Texas, they call guys like George 'a hard case'.
It wasn't easy being his brother, either. He truly enjoys getting people to knuckle under'."http://pseudoconservativewatch.blogspot.com/2006/09/why-are-pseudo-conservatives-addicted.html
