I've only done a few LAN parties in the last handful of years, and they weren't quite as magical as doing it as a teenager where you spend 75% of the time deciding on what to play and then figuring out how to crack it so everyone can play.
[1] Extra points if a player had participated in another LAN party with other people and had changed some or the other Windows network setting for that LAN party. "It worked last month and I did not change anything!" was always only true until the "and".
