For the final list in our 12-day holiday countdown, we've gone through all the holiday videos featured on YouTube Trends this month and pulled together a list of the Most Viewed holiday clips.

The biggest hit of the holiday season was the Hallelujah flash mob performance in a mall food court in Ontario, Canada. The holiday flash mob phenomenon was maybe the biggest and most widespread video trend of the season as well.

Though they didn't make the list we also saw: Some great SantaCon videos from San Francisco and New York. Santa bust a move, leak his naughty list, and rappel from an air force helicopter. Holiday mashups, zombies, camels falling, beer bottle carols, and dogs with hands. And got Christmas wishes from Alaska, New Zealand and even space. (And don't forget this dark, funny short from eastern Europe.)

The full list of the ones that did make it is below or you can watch them in a playlist here.

(May take a moment to load.)
