As far as "YouTube Treasures" go I don't think anyone is a bigger treasure then "Mr. Trololo".  his real name is Eduard Khil and he passed away from a stroke in a hospital in Russia after a stroke.

I still remember when my friend Flounder played it for me the first time. I laughed so hard and it's rare that we will be at a bar and not start belting out his song. He even made a appearance on "Family Guy". here is the treasure itself. Whether he meant to or not "Mr. Trololo" spread a lot of joy rest in peace.
