Miley Cyrus -- Wrecking Ball (Chatroulette Version)

2013 will be known as the year of Miley Cyrus. From tongue-wagging, to teddy bear-grinding and everywhere in between, Miley was constantly in the news. Her smash hit "Wrecking Ball" tells of the heartbreak she felt when ex Liam Hemsworth broke off their engagement.

The song quickly racked up 400 million plus views. However the Chatroulette spoof version injects some much-needed humor into an otherwise sad song.

Harlem Shake (original army edition)

Bauer's "Harlem Shake" got good reviews upon its release in 2012, but no one expected the cultural sensation it would become. Back in February of this year, outrageous videos started popping up all over the web of groups of people dancing to the catchy tune. The Norwegian Army version is the most popular of the hundreds of Harlem Shake memes.

PSY -- GENTLEMAN

"Gangnam Style" is the number one most seen web video in history. In fact, it's still racking up thousands of views a day. But it's so 2012. The world needed another song to waste countless hours listening to on repeat. Enter "Gentleman," South Korean pop megastar PSY's latest hit. It's full of offensive imagery but, like everything PSY does, it's all in good fun. The video pokes fun at sexism in South Korea and its catchy beat is hard to deny.

Volvo Trucks -- The Epic Split feat. Van Damme (Live Test 6)

You all know that Jean Claude Van Damme was one of the world's most popular action movie stars in the 1980s. However, did you know that in 2013 he is arguably the most limber man in show business? Van Damme proves this in an ad for Volvo Trucks. In an amazingly poetic performance he shows us that he can do a split between two moving 18-wheelers thanks in part to the stability and precision of Volvo Dynamic Steering.

Worst Twerk Fail EVER -- Girl Catches Fire!

It was the twerk heard round the world. Caitlin Heller attempts to twerk out to a song and it all goes well at first. Then she is interrupted by her roommate and catches on fire. It was a shocking video and all who watched seriously thought the young lady was hurt. The video was later debunked as a Jimmy Kimmel Live sketch. It's a funny video nonetheless. Miley Cyrus would be proud.
