The Tin Man has no heart.If you're going to stab someone (which we highly recommend not doing), the first thing you might want to do is get him someplace secluded so nobody, you know, witnesses it. If that's not possible, you would probably want to make yourself as inconspicuous as possible. You wouldn't want to, say, dress up like the Tin Man from "The Wizard of Oz" and gank somebody with a screwdriver right in Times Square.

Yet that's exactly what Gerald Brown did last night.

Brown, 50, from Harlem, apparently felt like the still unidentified CitySights tour employee was encroaching on his turf, which he protects rigorously. Just two days ago somebody saw him call a guy in a Spiderman costume an a**hole for stepping onto his corner. A fight started between the Tin Man and CitySights guy and words became blows became somebody getting stabbed with a screwdriver. Brown was arrested later, and the bloody screwdriver was found in his silver pants.

We know exactly what you're thinking -- the Times Square street performer circuit is in serious need of pimps to regulate this stuff.
