The giddy real estate mogul then launched into an impromptu comedy set for reporters, telling a string of risqué jokes in a comedy skit centered on marriage and the wife angle.
Harry Macklowe had announced to his wife in May of 2016, that he was leaving her for a new girlfriend, Patricia Landeau, president of the French Friends of the Israel Museum, located in Jerusalem, NY.
Multiple sources confirmed the septuagenarian billionaire was gallivanting around the Hamptons over Memorial Day weekend with his attractive new French girlfriend.

His act outside court Tuesday had several long quips including addressing a marriage where love is long lost: ‘A husband has been giving his wife incredible pleasure, beyond her wildest fantasies, for 30 years of marriage. But they always have sex with the lights off. One night she gets curious, leans over and flips the light switch on. She is shocked to see that her husband is using a vibrator on her. “I knew it, you jerk, explain the vibrator!” she says.’
“Explain the kids!” he says.
Macklowe is engaged to be married to 62-year-old mistress Patricia Landeau, a museum president, seemed unconcerned about the prospect of losing half of his fortune, as he cracked his wife jokes Tuesday.
He even suggested reporters check out the stand-up routines he’s posted on Old Jews Telling Jokes.
He griped that his wife,  who is an art-loving trustee of the Guggenheim Foundation, never laughed at his wisecracks.
He also complained about how she refused his offer to give her half his money — and instead served him with divorce papers as he arrived with his new gal pal in London last year.
Linda, 79, filed for the divorce in July after learning that her husband had put his French mistress up in one of his apartments at 737 Park Ave., less than a mile away from their home at The Plaza hotel.
Linda and her attorneys declined to comment.
Manhattan Supreme Court Judge Laura Drager ordered the two sides to “move this forward expeditiously.” Drager asked Linda for a list of information she wants to determine the value of her husband’s real estate empire.
