Wayne Brady, host of the CBS game show Let's Make A Deal, serenaded a gay couple after they got engaged on the show.

After Brady picked two men wearing matching German lederhosen outfits from the audience, one asked if he could give a “little shout out.”

The man got down on one knee and proposed: “Ron, will you marry me?”

An emotional Ron replied “yes,” fell to his knees and hugged his fiance as the audience clapped and cheered.

Brady serenaded the coupled with an improvised tune.

“Today's the day in which they'll cry and laugh. Today's the day that Ronald's gonna give him half,” he sang as the men slow danced. (The video is embedded on this page. Visit our video library for more videos.)

For eight years, Brady played James Stinson, the gay brother of Barney Stinson (played by Neil Patrick Harris), on the long-running CBS comedy How I Met Your Mother.
