If you listen to Giuliani, it’s like nobody did anything to improve the city except him. I’m not part of the history. Bloomberg’s not part of the history. It’s like, he did it. He’s the only one. That’s why he’s a little crazy.

Koch is criticizing what he sees as Rudy Giuliani’s self-mythologizing about New York City’s turnaround. By naming himself and Michael Bloomberg—mayors associated with earlier fiscal stabilization and later managerial reforms—Koch argues that urban improvement is cumulative and institutional, not the achievement of a single heroic figure. The remark also reflects the long-running rivalry and ideological differences among New York’s mayoral “eras,” especially over credit for crime reduction, quality-of-life policing, and economic revival. Calling Giuliani “a little crazy” is less a clinical claim than a rhetorical jab: Koch frames Giuliani’s insistence on sole credit as evidence of ego-driven distortion of public memory and civic history.
