Back Surgery

In 1997 both Neal and George had major back surgery after carrying one too many bathtubs full of caffeinated, carbonated, goodness. For any normal human beings this would have been a major setback, but Neal and George used the opportunity to have their spines replaced with naquadah powered fusion reactors. Their new spines allow them to perform unimaginable feats of strength, travel at incredible rates of speed, and communicate with ungulates. But don't ask them to, they're not proud of the side effects.
