Christmas Carol Flash Mob Takes Over Shopping Mall (VIDEO)

Thinking of doing your Christmas shopping in a mall over the next couple of weeks? A word to the wise: do watch out for festive flash mobs, like the one that took over this unnamed US retail emporium a few days ago. Their antics can really delay you.

As much as we approve of the sentiment here, we can't help noting they selected some of the most mournful Christmas carols going. And fancy kicking off with an obscure verse of 'O Come All Ye Faithful' that nobody knows. Pick it up a bit, guys! Honestly - we were so relieved when 'Go Tell It On The Mountain' kicked in after around three minutes, but even that didn't last long.

Oh, and do look out for Mary, Joseph and Baby Jesus making a guest appearance in the coffee shop towards the clip's end. Apparently, they'd initially wanted to go to the inn for their lunch - but there wasn't any room. (Sorry.)

When all is said and done, though, we've got to be honest: we preferred this recent Christmas medley...
