If at first you don’t succeed, rob again.

That was the slogan adopted yesterday by a determined robber who targeted adjacent banks in Elmhurst, authorities said.

He first hit the HSBC branch at 87-03 Queens Blvd., near 55th Avenue, at 11:42 a.m. but scored zilch, cops said.

Still desperate for cash, he simply trotted next door to a Citibank, passed a demand note to a teller and fled with a haul estimated at between $8,000 and $10,000, cops added.

The crook is believed to be in his 40s, and was last seen wearing a gray tank top, jeans shorts and a black baseball cap.

An unidentified man was found dead yesterday behind a building in Astoria, authorities said.

The man, believed to be in his 20s, was found at 4:27 a.m. on the ground on Steinway Street near 28th Avenue with his pants zipper undone, cops said.

It appears as though the man may have fallen from a window, cops added. Investigators are looking into whether he was a peeping Tom.

The medical examiner will determine the cause of death.

A former employee of a popular Midtown pizzeria viciously attacked two workers in the eatery’s kitchen, authorities said yesterday.

Guillermo Gutierr, 29, allegedly broke through the locked doors of Two Boots Grand Central, at 89 East 42nd St., at 8:30 p.m. Saturday and punched an employee in his right cheek.

Gutierr left, but returned 10 minutes later and socked another staffer in the left cheek, cops said.

Responding officers arrested Gutierr. His alleged victims were not seriously injured.

It’s unclear what triggered Gutierr’s rage.

He needs to learn some manners.

An enraged 62-year-old man used his cane to attack a guy 41 years his junior during an argument over who should have said “excuse me” in a Boerum Hill housing project, cops said yesterday.

Larry Peterkin was driving his motorized scooter into the elevator at the Wyckoff Houses on Third Avenue and Baltic Street at around 1:30 p.m. Monday when he nearly barreled into the 21-year-old victim, cops said.

The two started fighting over courtesy when Peterkin allegedly became so steamed that he jumped off his scooter and whacked the victim with his cane, cops added.

He also allegedly punched the victim in the face and bit his arm, causing minor injuries.

“I know we have a problem here. He should have said, ‘Excuse me.’ I don’t have to say excuse me,” Peterkin allegedly told arresting officers.

He was charged with assault, weapons possession and menacing.

Someone needs a driver’s-ed refresher course!

A speeding, unlicensed teen driver crashed into an NYPD patrol car after he blew through a red light in Egbertville, authorities said.

Justin Turner, 18, was allegedly rocketing along at 50 mph in a 2006 Lexus sedan at about 1:20 a.m. Wednesday when he shot through the intersection of Manor Road and Rockland Avenue and slammed into the cruiser, court papers claim.

The two officers in the cruiser suffered minor injuries after the impact sent their vehicle careening into a guardrail.

Turner was charged with reckless driving, assault and driving without a license, said a spokesman for DA Dan Donovan.

The victim was unharmed, and the thieves fled with the loot.
