The expert prankster told the ABC late-night host Tuesday night that the entire "secretly filmed" conversation with the ex-convict was conducted in a hotel room in Las Vegas in hopes that O.J. would confess to murdering Nicole Brown Simpson and Ron Goldman. If you saw the episode, you remember Cohen suited up as faux Italian billionaire Gio Monaldo for the undercover interview that didn't pan out as Cohen had hoped.
"The last time O.J was in a hotel room in Vegas, he ended up in jail," Cohen explained. "So the aim was to-- I was trying to get him to confess to the alleged murders -- which was ambitious!"
Cohen said he trained for the role with one of the top interrogators of the FBI, adding, "not very successfully because I didn't get O.J. to confess."
"I said that I was representing an omani sheikh (ruler of the country of Oman), and the omani sheikh would pay O.J. Simpson to confess to the murders -- pay him $2 million -- because he wanted to kill his own wife," Cohen explained before going into character.
"He absolutely loves you. He wanted to kill his own wife. You are the greatest wife killer," Cohen said in a heavy Italian accent, adding that Simpson's response was always, "No, no, I didn't kill my wife."
Cohen said his response as the Italian billionaire was, "I didn't kill my wife, either. She just got so depressed, she put herself in a body bag, she filled it with rocks and she pushed herself over the yacht. That's right."
He told Kimmel Simpson simply "laughed and laughed."
