I know I guy that knows a another guy that once met with a fellow runescape player. He posted lots of runescape parody videos, but then JaGeX requested Youtube to ban his account and remove the videos... Bummer....
So..... he looked for something else to parody on.... This one might be the currently most know parody on youtube:http://www.youtube.com/watch?v=9xSwlll478k
PS. I have the original song, without vocals ^_^
PSS. Add him in-game if you want: Town Idiot25
