Earlier this month in Welland, Ontario, a seemingly ordinary lunch hour at the Seaway Mall Food Court took a surprisingly festive turn when singers, who planted themselves in the crowd, suddenly broke into song, singing "Handel's Messiah."
Flash mobs similar to this one, where people sing or dance spontaneously, have been popping up all across the U.S. and Canada.
The video from Welland has more than three million hits on You Tube.
