Joe Arpaio is the latest victim of Sacha Baron Cohen's satirical "Who is America?" prank show.

The former Arizona sheriff was tricked into believing he was appearing on a Finnish YouTuber's video.

Baron Cohen, posing as the YouTuber, asked Arpaio whether he would receive a blowjob from President Donald Trump, to which the sheriff replied: "I may have to say yes."

The sheriff, who is a close ally of the president, also said he wouldn't be surprised if Trump had participated in the most salacious claim made by the infamous dossier.

Arpaio is the latest in a string of prominent Republicans to be deceived by Baron Cohen on his TV series.

Sacha Baron Cohen's ritual humiliation of prominent Republicans has once again borne fruit — and this time it's in the form of Joe Arpaio.

In the latest episode of Baron Cohen's satirical sensation "Who is America?" the actor posed as a Finnish YouTuber called OMGWhizzBoyOMG (real name: Ladislas Kekkonen) who invites the self-styled "toughest sheriff in America" on his show.

In reference to an unverified claim in the explosive Trump dossier, Baron Cohen asked Arpaio, the former Arizona sheriff who is a close ally of President Donald Trump, whether the president might have had a golden shower, to which the sheriff replied: "Wouldn't surprise me."

Baron Cohen then asked the sheriff: "If Donald Trump calls you up after this and says, 'Sheriff Joe, I want to offer you an amazing blow job,' would you say yes?"

"I may have to say yes," Arpaio replied.

The show also features Arpaio arguing with a plastic Shopkins toy — specifically, an anti-firearms D'lish Donut.

"Delicious doughnut, you have to understand that you have to follow the Constitution and the law and allow people to have guns," he's seen telling the doughnut.

Baron Cohen tells Arpaio that unlike D'lish Donut, he is a staunch gun advocate, boasting a collection of more than 43.

"Oh yes, I've been collecting them for the upcoming race war," Baron Cohen says.

He also gives "Finnish" addresses to the camera throughout the segment, which are clearly gibberish.

The former sheriff responded to being duped by Baron Cohen back in July, saying, "I was kind of mad at myself."

"I started to get a little angry, a little sad, but I went through it," he said.

Arpaio is best known for illegally detaining Latinos and keeping inmates in brutal jail conditions during his 24-year tenure as sheriff of Arizona's Maricopa County. His aggressive tactics ultimately led to a criminal conviction after he violated a court order in a racial-profiling case. He was let off the hook when Trump issued his first presidential pardon to Arpaio last August.

The former lawman announced in January that he intended to run for US Senate. He is the latest in a string of prominent Republicans to be deceived by Baron Cohen as part of "Who Is America?"

Former Vice President Dick Cheney signed a "waterboard kit" for Baron Cohen, and the Georgia state lawmaker Jason Spencer resigned after screaming the N-word and exposing himself on the show.
