Viral videos are a funny thing.
First, there was the song "Somebody That I Used To Know" by Gotye (pronounced Go-Tee-Yay) The video for that has been viewed 67 million times.
Then came the cover by Walk On the Earth. 50 million views in its own right.
Now, the parody of the cover, this one by Key of Awesome. Almost half a million views in a day and a half.
