As the decade draws to a close, Unruly staffers are getting quite nostalgic as we look back on a year of amazing viral videos. So, after consulting Unruly's own Viral Video Chart, we are very pleased to offer you the rundown of the most talked-about videos of 2009 (measured by the number of posts and tweets about each piece of content), the nuggets of viral gold that have kept your iPhone busy, your facebook profile jam-packed and kept you all tweeting to your heart's content throughout the year. So here they are, in reverse order. Enjoy...and here's to 2010!

10: Her Morning Elegance by Oren Lavie

This delightful gem of a video is a little piece of stop-motion genius. Its heartwarming charm is guaranteed to bring a smile to your face. Not only did it make the Top Ten in the Viral Video Chart; it was also nominated for a Grammy in the category of "Best Short Form Music Video".

9: JK Wedding Dance Entry

A piece of viral heaven!! It seems that many of you passed on this very funny video with gusto!! And why not? Everyone deserves a lesson in how to do 'Getting Married' the truly unforgettable way!!

8: I'm Yours (Ukulele)

So what do you suppose is the number one reason for sharing videos? Humour? The desire to make others smile? Of course, it is! And this is why this little slice of brilliance made the top ten this year: it is very, very funny!! I love the little 'itchy nose' thing he does throughout his rendition!!

7: Me Da Meu Chip Pedro. Manda Meu

This one doesn't make much sense unless you speak Portuguese, I'm afraid. Nonetheless, this Brazilian video was incredibly popular in 2009, spawning dozens of copycat videos, including this Obama-esque parody here.

6: Surprised Little Kitten

Somethings never go out of fashion. Cute kittens have long been a staple of online video culture, and this one is cuter than most.

5: Social Media Revolution

A powerful micro-documentary, which does a really good job at conveying the relevance of social media in the digital age. Surprising statistics coupled with Fat Boy Slim's, very apt, 'Right Here, Right Now' soundtrack saw this video clock up 12,00 tweets in 2009

4: The Muppets Bohemian Rhapsody

Animal's performance as Freddie Mercury is the stand-out act in this retrotastic queen of clips.

3: Susan Boyle in Britain's Got Talent

Unless you spent 2009 living on the Moon, you'll know that Susan Boyle conquered the entertainment world this year with her unexpected star turn on UK Talent Show, Britain's Got Talent.

2: Piano Stairs

This delightful piece for Volkswagen demonstrates that the simplest ideas are often the most effective, with the potential for massive viral appeal. Echoing the famous FAO Schwartz scene in Big, this video is sure to inspire similar pop up installations in cities across Europe. Can't wait until it comes to a tube station near me!!  

1: Lady Ga Ga- Bad Romance

This creative cacophony references everything under the sun, and perfectly mirrors Ga Ga's own eclectic and somewhat crazy style!! Oh, how we loved it...with nearly 50 million views, Twitter awash with Ga Ga activity and a place at the top of the Viral Video Chart for much longer than is considered normal, Bad Romance was one of the most talked about videos of 2009. We await, with bated breath, for more crazy Ga Ga in 2010.

btw here's what Reuters had to say about this year's chart when they came into the office to chat last week:
