Stone, an inmate at central Florida's Lake County Jail for property damage charges, figured out that while the jail charges prisoners for calls, it refunds them twice for incomplete ones. Pretty good score. So he set about making 77 incomplete calls in three hours, earning him more than $US1250. Enough to post bond, and even have 50 bucks in freedom money.
Our hero wasn't free for long, though. The screws got wise when 256 other inmates tried the same thing. Stone was picked up shortly thereafter, and they fixed the glitch. But you can't knock a guy for trying. [Google News, ABC News]
