http://www.youtube.com/watch?v=7Vwhr8v7ikc If you thought that in 2013, the virtual world was concerned mostly with the Harlem Shake, Pharrell Williams and Miley Cyrus then you are very much mistaken. There is one craze that took over YouTube like no other, that could make almost any song suddenly hilarious. Yes, 2013 was the year of the goat. It's not technically a specific spoof video but it's far too good not to mention. Ever since the world caught onto the videos of goats who yell like humans, the internet went wild for replacing words and lines in well-known songs to audio of screaming goats. It was definitely one of the most bizarre virals of the year however for some reason it is absolutely hilarious. So much so that it led to the spoof advert for 'Now That's What I Call Goats 13' and the launch of the website Goat Roulette basically Chat Roulette replaced by music videos with singing screaming goats. Some of the most notable versions include Whitney Houston's 'The Body-Goat', Nirvana's 'Goat-shaped Box', Gotye's 'Somebody that I used to Goat' and Taylor Swift's 'I Knew You Were A Goat When You Walked In'. Go goat!
