It gets a little complicated. Here's the long and short of it.
Lightning is RF energy (radio). Meaning it travels on the outside of the wire, not through it. This lets it jump accross an open circuit and continue on in its search for earth ground. And that's the 3rd pin on the power plug. Now don't go and yank out the 3rd pin because you need it in day to day operations. To give you the short answer. Flipping the switch on the power strip just don't get it. Unplug it and the connection to the outside world.
