According to the news-team at CW31, a California paraplegic man regained the power to walk after being bitten by a brown recluse spider.
When you dig down a little, you realize that the (non-Radioactive) Spider-Bite just prompted him to go to hospital and made the staff aware that he still had some feeling left in his legs. Even so, it's a cool story. Thanks to Cam for pointing us at this one.
