Eduard Khil, better known as "Mr. Trololol" or "The Trololol Guy" has passed away at age 77.
His vocalized version of "I'm so glad I'm coming back home" was a HUGE internet hit/meme on the web and is still popular today.
He was actually pretty cool about it and even re-sang it later in his life. Even though I don't know him, someone who made me smile/put me in a good mood has passed away. :(
