Mat Investigates: Converting an NES Controller to an MP3 Player

When you saw the title of this post, you probably thought one or more of three things:
What?!?!,
How?!?!?, or
NERD!!!!!
All that aside, It can be done. Here's what you'll need:
An NES controller, an MP3 player (a Coby 512mb one is the one used in the instruction.), and internet access to go to http://www.instructables.com/id/NES-Controller-MP3-Player/ for step by step instructions.
If someone actually makes this, please send some pics or a video of it working to thematblog@gmail.com. I want to see one.
