Parody #1_Walk Off the Earth's spoof of Gotye's, Somebody I Used to Know...and yes, they really are playing one guitar!
Viewed 143,342,631 times, this was the second most popular viral youtube video of 2012...Gangnam Style was #1, but I like this one a lot better! Not sure what's happening there with the guy on the end in the knit cap & the profuse arm hair, but I agree with one of the commenters who said that he resembles a sea captain... LOL
