Looks pretty real, but check MSNBC, "Lightning striking twice? Maybe not even once":
The first sign that the video might be fake, according to Vladimir Rakov, electrical engineer and co-director of the University of Florida Lightning Research Group, is that people almost never survive direct lightning strikes like the one shown in the video. "The chance of survival in the case of a direct strike is essentially zero," Rakov told Life's Little Mysteries. That's because lightning bolts emanating from storm clouds convey a gigajoule of energy, he explained — which is about enough to melt a ton of steel.
The vast majority of the 240,000 people who survive lightning strikes worldwide each year do not actually get hit directly. "They are struck by 'side flashes,'" Rakov said. "Lightning might strike a building near them, for example, and there's a side flash that jumps to them carrying a small fraction of the original lightning bolt's energy. In that case, they can survive and even walk away."
