One thing I do in my spare time is scour YouTube for Juggalo videos. After around four hours of doing that, I then search for musicians who like to put their own spin on the Super Mario Bros. theme song. Strange that no Juggalos have covered it...

Here's drpez12, who has more musical talent in one hand than the crappy garage band who is always waking up my neighborhood at 1:00 in the morning. His version of the Mario theme is pretty awesome.
