Each day, Mashable highlights one noteworthy YouTube video. Check out all our viral video picks.
A New Jersey mall abruptly transforms into a stage for a short musical about Santa. One man breaks into song about how "you're never too old, too old to sit on Santa" and soon a handful of mall occupants join in.
The mastermind behind this flash musical is Improv Everywhere, a comedic group known for causing fun, attention-grabbing scenes in public. You may remember the group's flash musical about social media in May in which conference "attendees" sang about the joys of sharing stuff online (see the first video in the gallery below).
The mall Santa musical is part of Improv Everywhere's Spontaneous Musicals project. To see the other videos, flip our gallery below. For a behind-the-scenes look at how the Santa musical was created, click here.
