A wedding reception is a great occasion for people young and old to mingle—and things always get interesting when they start dancing.

One senior was ready to show who's the boss of the dance floor, as soon as the DJ started playing Michael Jackson's Billy Jean.

The balding, eyeglass-wearing gent is named John Lawless Jr. and he stole the show with his spot-on moves, including floor drops that floored everyone who gathered round at the Long Island reception.

"Oh my goodness gracious, I can't believe a story has been done on me," he exclaimed, after the WS video began going viral on NewsBreak. "Totally blown away."

"It makes me want to dance all over again," said John, who works for the US Postal Service.

Watch his awesome moves in the video below—a one-minute confirmation that you can't judge a book by its cover.
