Via Boing Boing, here’s the (somewhat dubious, if you ask me) story of a rent-a-geek who accepts sexual favours for services rendered. Here’s his pay scale:
It’s basically all about the time I spend: If I’m working for one or two hours, I’d like a blow job. An orgasm for every two hours of service is pretty fair. If it’s something simple that I can fix in 15 minutes, I’d like to get a foot massage.
Hurray for the barter economy. That said, a foot massage don’t pay the cable bill. Interestingly, his (or a copycat’s–there appear to be several) ad has been removed from the Sacramento Craigslist.

Hmm, might be interesting to look at the distribution of time spent on a repair. You might be forgiven for predicting a flat spot in the range between 20 and 50 minutes.
