This blog has been a long time in the making -- the original file was dated October 7th. In any event, I'm proud to (finally) present to you: booty's babes, Sexy Geeks v1. The girls were rated on face, body, personality, and brains -- combined scores determine the ranking. In the event of ties, ranking was determined by GNN men.
Additional fun details have been added for your amusement. And yes, there will be additional installations with an updated ranking at the end of my list. Feel free to leave suggestions for upcoming lists!
