I'm a big fan of the fantastic sound design of Diablo III. I'm also a big fan of Koji Kondo's original theme for Super Mario Bros.
So as you can imagine, I got a kick out of this remix by YouTuber Tyler73123, who puts the sounds of Diablo III behind the music from Mario. OK so, he really just syncs up the sound effects to the rhythm of Mario, but it's still pretty funny.
My, what a nice sense of musicality you have, Diablo III! You must knock 'em dead at parties.
