They’re taking a whack at coming clean.

Gambino crime family capo Joseph “Joe Brooklyn” Lanni and six of his fellow wiseguys copped guilty pleas Friday for violently trying to take over the Big Apple’s garbage business.

“I knew that agreeing to do this was against the law,” Lanni flatly said, apparently reading a boilerplate definition of racketeering during his plea in Brooklyn federal court.

Lanni, 54, who also goes by the mafia moniker “Mommino,” headed a sprawling racketeering enterprise engaging in extortion, witness retaliation and other crimes — with an audacious bid to put the city’s trash and demolition industry under its thumb, federal prosecutors said.

The pleas follow a probe from the Eastern District of New York feds that led to a 16-count indictment in 2023.

An ensuing takedown, including arrests in Italy, rounded up a crew of Gambino made men and associates with nicknames such as “Vinny Slick,” “Uncle Ciccio,” “Twin” and “Fifi.”

Made man Diego “Danny” Tantillo, 50, wore flashy silver sunglasses in the courtroom as he pleaded guilty to charges related to extorting a New York City-area carting business.

Tantillo menacingly threatened the business’ owner with a metal baseball bat, demanding monthly payments, court papers state.

When the owner stopped making payments, Tantillo’s men set fire to the man’s front steps, let air out of the tires of his trucks and even threatened to cut him in half, the documents allege.

One mobster — Francesco “Uncle Ciccio” Vicari, 64, who also pleaded guilty Friday — “acted like the ‘Last of the Samurai’” as he picked up a knife and told an associate to bisect the hapless owner, a wiretap revealed.

“Get this axe and you make him – two,” he allegedly said.

Tantillo, who also allegedly arranged a hammer assault on another demolition company’s employee, received at least $4 million in payments from his ill-gotten schemes — and dutifully “kicked up” the proceeds to Lanni, prosecutors said.

Lanni was also implicated, but not charged, along with Vincent “Vinny Slick” Minsquero, 38, in a wild fracas in a Toms River, New Jersey restaurant in September 2023, court documents allege.

The mobbed-up pair got in an argument with another patron, prompting the restaurant’s staff to ask them to leave.

Minsquero damaged a painting and punched wall, while Lanni said he would “burn this place down with you in it,” court papers state.

Minutes after making the threat, Lanni bought a red gas container, walked to a pump and tried to fill it before Minsquero wrested it from him, the documents reveal.

Still fuming, Lanni called the restaurant 39 times — with one threatening call being captured on Toms River cop’s body camera.

“Apologize to me,” Lanni could be heard saying, the documents state, before he repeated, “Beg for my forgiveness. Beg for my forgiveness. Beg for my forgiveness . . . Beg. Beg. Beg for my forgiveness. Beg. Beg. Beg for my forgiveness. Say, ‘I’m sorry, Joe.’”

The ordeal didn’t end there — two men came back to the restaurant around midnight, punched the owner in the head, put a knife to his neck and threatened to kill him, court papers state.

The owner’s spouse was also knocked to the ground and beat by the two men.

Judge Frederic Block, a joke-cracking wiseguy of the standup comedy variety, told Lanni he faced a sentencing range between 6.5 and 8 years, before implying the ultimate prison bit could be shorter.

“You are putting your life in my hands,” the judge said, before deadpanning, “I’m talking real street talk to you.

“You’re willing to roll the dice?”

“Yes, your honor,” Lanni replied.
