Sounds like something from Seinfeld.

A Hasidic man, in a racist meltdown over a parking space outside a Brooklyn firehouse, slammed his car door into a Black firefighter’s knee and called the man a “n-----” before fleeing the ugly scene, authorities said Friday.

The hate-fueled motorist slapped another firefighter’s arm and blocked a firetruck inside the bays at Engine Company 211-Ladder Company 119 on Hooper St. in South Williamsburg during his rampage as the Bravest squared off with the unhinged man last Sunday, according to officials.

Jacob Deutsch, 55, allegedly hurled the racial epithet at the 42-year-old firefighter and threatened to “go to war” against the man’s colleagues after he was threatened with a summons for pulling his brand new Acura in a spot reserved for FDNY vehicles.

But authorities said Deutsch did not go quietly.

“Hey a-------, don’t write a ticket!” he screamed during the 10 a.m. confrontation, according to court papers. As he pulled out of the first spot, Deutsch then parked directly outside the firehouse’s bay doors, blocking a fire truck that was pulled outside to be washed. He then allegedly exited the vehicle to threaten the firefighters.
