This had an immense purchase on my imagination. I knew the only thing that could kill Superman was Kryptonite. I used to dream the sky was full of this stuff, flying back and forth, glowing and green and lethal.
I thought we should have a stash of it in case Superman let his power go to his head and decided he ruled the earth. . .just a few pebbles of the stuff to straighten him the fuck out, if need be. The idea off glowing green Kryptonite seemed, in a weird way, seductive to me. This alien rock form that glowed like a jewel in the dark, seemed musical and deadly and sexy. . .like you wanted to crush it up and snort it.
