Jake’s bar bout

BOXER Jake LaMotta was famous for dishing out punishing beatings in the ring.

But the man who inspired Martin Scorsese’s 1980 “Raging Bull,” and died this week at 95, wasn’t so tough when former world featherweight champion Willie Pep was around.

LaMotta (inset) was hanging out in a Seventh Avenue saloon owned by Pep when a hulking Japanese man approached him, reports The Post’s Kirsten Fleming.

“He was a collector for the Jewish loan sharks,” said director Matt Cimber, who helmed the original television series “GLOW: Gorgeous Ladies of Wrestling.”

As the man kept tapping LaMotta to grab his attention, the bruiser continued to ignore him.

“[He] keeps bumping Jake. Finally the guy got really angry and was losing his patience. He took his elbow and hit him right in the back of the neck,” said Cimber, who was having lunch there at the time.

“Jake turned around and belted this guy ... The guy just folded right to the floor,” he said. “[Pep] came out with a club and started swinging it [at LaMotta] and said, ‘ Get out of here, you bum.’ ”

LaMotta profusely apologized as he dodged the swings.

“Jake is going, ‘I’m sorry, Willie. I didn’t mean it.’ Jake just took off out the door,” Cimber said.

“Nobody messed with Willie Pep.”
