One parody intrigued me enough that i ended up following some links and reading some background to figure out how it came to be.
Like most other people i suspect, i've heard bits and pieces of "Somebody That I Used to Know" a number of times, but i'd never seen any of the videos before.
So in 2011 Gyote released the original video, which i thought was okay but nothing spectacular.

There were a number of covers of it, but one of the more famous ones was by "Walk off the Earth", who had a gimmick where all five members of the band were playing a single guitar at the same time. It's an amusing trick, but i'm still kinda meh about the song.

So then "Key of Awesome" made a parody of the video of the cover band, which i find hilarous.

But anyways, as long as i'm at it, here are some of the other parodies that i thought were decent (though not quite as good as the ones i've gushed about in the past =)

And i'm pretty sure i've posted these ones before, but they came up on the list, and they're awesome :)
