Larry King for N.Y. Marriage Equality

Larry King, the Emmy Award-winning TV and radio host, joins the video series for marriage equality from the Human Rights Campaign.

In the new 30-second spot, the former host of Larry King Live and Brooklyn native pokes fun at his own marriage record, which includes eight marriages to seven different women.

"I know a thing or two about marriage, maybe three, maybe four," he says. "Some of us can get married again and again, and others can't get married at all. Can't figure that out."

The appearance from King, 77, could help boost support for marriage equality among viewers age 55 and up, where polls consistently show that young people drive the growing support for the issue across the country. A vote on the marriage equality could take place in New York by June if a coalition of advocates and governor Andrew Cuomo can garner the 32 votes needed to pass the measure in the senate, where the bill failed in 2009.

"As New York prepares for a vote on marriage equality, we are thrilled to have such an iconic native New Yorker and one of the nation's most recognizable and respected TV personalities lend his voice to the cause," said Brian Ellner, senior New York strategist for the Human Rights Campaign, one of five LGBT organizations in the New Yorkers United for Marriage coalition.

The New Yorkers for Marriage Equality campaign, which has appeared online and on the city's Taxi TV, features prominent New Yorkers to move viewers to lobby their state lawmakers. Other videos in the New Yorkers for Marriage Equality campaign so far have included Barbara Bush, daughter of former president George W. Bush; New York City mayor Michael Bloomberg; former mayors Ed Koch and David Dinkins; former police commissioner Bill Bratton and Rikki Klieman; Robert F. Kennedy Jr.; Joan Rivers; Whoopi Goldberg; Lucy Liu; Kyra Sedgwick and Kevin Bacon; Russell Simmons; Bill T. Jones; Julianne Moore; Ethan and Ryan Hawke; Sean Avery; Christopher Meloni; Moby; Brent Ridge and Josh Kilmer-Purcell; Fran Drescher; Mark and Sunrise Ruffalo; chefs Mario Batali, David Chang, and Tom Colicchio; Julianna Margulies and husband Keith Lieberthal; Jeanne Moutoussamy-Ashe; Kenneth Cole; John Slattery; and Daphne Rubin-Vega.
