Peter Parker, aka Spiderman, was webslinging happily through the city. It was a lovely day-- the sun was shining, the birds were twittering merrily, and, best of all, no enraged supervillains had attacked in more than a week! Sure, there was the occasional small-time crook to apprehend, but at least they didn't have superpowers, more money than you could shake a stick at (in the case of Kingpin), or other amazing-yet-used-for-evil talents.
Something caught Spidey's eye. He nearly slammed into the brick wall of an apartment building when he realized that, close beneath him, was his boss, J. Jonah Jameson.
He was in an argument (which wasn't really anything new), but the strange thing was he seemed to be arguing with two other identical versions of himself.
"Oh, well," said Spiderman. "I guess I have to help sort this out. It's the heroic thing to do."
He landed gracefully on the wall of a nearby building and crawled down to the ground.
"Well, hello there," Spiderman said. The three J. J. J.'s turned to face him.
Perhaps, if I ask the right questions, the fakes will reveal themselves... thought Spiderman.
