If Batman was reduced to donning his costume only to pose for pictures with tourists in Times Square for meager amounts of money, he'd be understandably pissed off. Times Square Batman gets into an intense altercation with a man who claiming he pushed his son, then threatened him. Perhaps acting under Commissioner Gordon's directive, an officer allows Times Square Batman to cool off.
Times Square Batman gets so heated that Spider-Man has to transcend comic book universes to calm him down. Shit gets real in the real Gotham City, and Times Square Batman nails the brooding, caped crusader act. Christian Bale would be thoroughly impressed.
The best line? "You think he gangster but he ain't no gangster. I know a gangster when I see one." The Dark Knight knows better than anyone that ain't no such thing as halfway crooks.
