In the days of the Yale dress code,

Bush would walk into the dining hall in jeans and a T-shirt, tossing a necktie on top.

And not just any T-shirts. Bush was particularly fond of the garish orange T-shirts (with matching orange socks) issued by the intramural sports program.

He spent nights with friends in Davenport, his residential college, perfecting a game he invented called "squash hockey." Using fireplace grates as goals, Bush and his friends would play hockey in Davenport's downstairs squash courts, "whacking" a tennis ball around the courts in the hours after midnight.

Bush was known to nearly every member of his graduating class of 1,000, his friends say. He was affable, funny and just the slightest bit odd.

For example, his classmates had never seen a certain Yale undergraduate naked, so George W. Bush took it upon himself to change that. In a show of dedication, Bush camped out in front of the young man's shower and waited for him to emerge.

One hour passed. Two hours passed. Bush continued to wait. And after three hours, the joke was on him: his prey stepped out of the shower fully clothed.

Bush was also "a notorious slob," Walker says, although he bought his clothes at prep school clothiers J. Press and Brooks Brothers.
