Senior Citizens "Moonwalk" to YouTube Fame

They're old enough to be Billie Jean's grandfathers, but age doesn't stop three California seniors from busting a move to the Michael Jackson classic.

In one of the latest YouTube sensations, 77-year-old Kurt Bourhenne, 81-year-old Bert Carroll, and 71-year-old Frank Tripoli - also known as "The Awesome Threesome" - show off their moves, deftly shifting from grabbing at ostensibly bad backs to grabbing their crotches.

The men performed the dance routine to "Billie Jean" during a Texas hold-'em party at their Leisure World Senior Community in Seal Beach, Calif., a few months ago, according to CBS station KCAL-TV.

Carroll's daughter, who also choreographed the routine, posted it online, creating some new found fame for the gray-haired dancers. The clip has been viewed more than 1.1 million times.

"I'm thoroughly amazed at that many people watching that!" Kurt Bourhenne told KCAL.

While the men all have music and dancing backgrounds, they concede dancing to the King of Pop was no easy task.

"I think we could spin, but we'd end up with vertigo," said Carroll. "You wouldn't see us for a week!"

Now that fame has found them - they're being stopped for autographs at the senior center - "The Awesome Threesome" is on the lookout for a new challenge.

"We ought to do Lady Gaga," Carroll said.
