A New York developer is willing to give up half of his $2 billion fortune just to end his messy divorce case — and he can’t stop laughing about it.

Developer Harry Macklowe, 79, was in a joking mood outside a Manhattan civil courtroom Tuesday as he talked about handing his wife, Linda Macklowe, a cool $1 billion so she will sign legal papers freeing him to be with his younger French gal pal.

“As soon as this divorce is over, I’m getting remarried,” he declared after a hearing into his breakup with his spouse of 58 years, who has thus far not agreed to his offer of a 50-50 financial split.

The giddy real estate mogul then launched into an impromptu comedy set for reporters, telling a string of “Take my wife — please”-style jokes straight from a Henny Youngman routine.

The act included several long quips such as this one: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.
