I wonder if the following, one of my favorite tidbits from the book, made it into the movie?
[After it is revealed that Ginny, Kelly, and Jenny were ranked the #1,#2, and #3 hottest girls on campus by Facemash there is the following aside.]
Tyler had to smile. Jenny, Kelly and Ginny were arguably the three hottest sophomore girls on campus. They'd been freshman roomates as well, put together supposedly at random. Except nobody on campus really believed it was random--especially since someone figured out that the last five digits of their freshman dormroom phone number turned out to be "3-FUCK." The Harvard housing office was notorious for bizarre little pranks like that. Putting kids with similar names in the same rooms. Tyler's freshman year, there was a Burger and Fries, and at least two Blacks and Whites. And then there was Jenny, Kelly, and Ginny, the three hottest blondes on campus, in a room with the phone number 3-FUCK. Someone probably needed to get fired.
