Of Metrocards and John Rocker

Somebody discovered that if you take a New York City–MTA Metrocard, with no money in it, and bend it in a certain way and back, you wound up with an unlimited-ride card (or until the MTA remotely stops the card access to the subways and train). Should that be considered magic for the modern age?

Another thing: Guiliani is doing the unthinkable: Mr. “We can kick your city’s ass” is suggesting New Yorkers to be–ugh–nice–when John Rocker takes that fateful ride on the 7 train this Thursday. But I don’t want to. What should I do?
