A lecherous Manhattan art dealer allegedly got so high at a holiday party he picked the lobster off people’s plates, pulled them apart with his mouth and tossed them around, according to a lawsuit.

Todd Merrill, an “art furniture dealer” with studios in Manhattan and Southampton, put on the bizarre display at a December 2016 bash for employees of his Todd Merrill & Associates studio, claims former business director April Walker.

Walker, who accused Merrill of firing her after she repeatedly refused his creepy come-ons, claims Merrill was so “high” at the event he also slapped a woman’s behind, and sat the wife of an employee on his lap while “bouncing her up and down,” according to court papers.

But nothing could quite match the crazy crustacean display.

“At different points during the evening when Merrill got up from the table to go to the restroom, he picked up the lobster remains on several people’s plates – including Walker’s – and, while standing, pulled them apart with his mouth and hands and threw them back on the table after he was done eating,” Walker claimed in her Manhattan Federal Court lawsuit.

Days after that party, Merrill canned Walker via an email, claiming she was “not the best fit” for his company. Merrill spent months propositioning Walker before firing her, she charges in the legal filing.

“The worst of Merrill’s behavior occurred when he was intoxicated or under the influence of a controlled substance, which happened often,” charged Walker, 42.

The sexual harassment allegations “are false, and can be proven so,” Merrill’s spokeswoman said.

“During the time that Ms. Walker claims she was sexually harassed, she had an attorney and was unsuccessfully negotiating the terms of an employment contract with Mr. Merrill that gallery employees sign. She wrote to Mr. Merrill, ‘I love the gallery and feel it is a great long-term fit for both of us,’” spokeswoman Barbara Dixon said.
