Geeky guys of the Valley, take note. Ever seen those licentious late-night commercials for local interactive date lines? Usually they're squeezed between the oh-so-mockable Goldberg & Osborne advertisements, starring hot-to-trot hotties who probably wouldn't let your unphotogenic ass buy them an overpriced martini at Myst. While these intimidating adverts have kept you from calling, the truth is that these beauties are in the minority on Livelinks, the most popular of the local chat services. Populated by plenty of dog-faced desperate housewives and other less-than-lovely ladies, the line's a veritable sexual smorgasbord of females looking for phone fun or an overnight rendezvous. Stay alert for ladies on the lookout for "generous gentlemen" (read: prostitutes) or trannies out to play the crying game (not that there's anything wrong with that). So if you can somehow sweet-talk some honey into slipping you her location, give it a shot, Ace, 'cause he who hesitates, masturb . . . well, you know the rest.
