NEW YORK—Morty Kaufman and Lee Kaufman, the adorable elderly couple who became an internet sensation for their poignant Swiffer commercial last year, attended a Shen Yun Performing Arts performance with their family on the afternoon of Jan. 12 at Lincoln Center’s David H. Koch Theater.

“I was retired for 30 years and now I’m a screen actor,” said Mr. Kaufman, who accidentally starred in a Swiffer commercial that taped the 90-year-old couple’s bona fide reaction to using Swiffer products for the first time. The video went viral.

When Mr. Kaufman is not making commercials, or taking naps, he likes to goes to the theater, he said. Morty appreciated the grace of Shen Yun. He also said he particularly enjoyed the storytelling traditions of classical Chinese dance.

Shen Yun is a New York-based classical Chinese dance group formed in 2006. Leading Chinese artists founded the non-profit dance group with hopes of revitalizing traditional Chinese culture.

Each dance is accompanied by a live orchestra and a high-tech digital backdrop.

Shen Yun has story-based dances that feature Chinese myths and folklore, as well as courageous tales about historical Chinese figures.

“There’s so much artistry here,” Mrs. Kaufman said. “They are so coordinated with what they’re doing together. It’s just so pretty that you get carried away.”
