If you're bored at work today, do yourself a favor and have a background tab tuned to www.mariomarathon.com. It's their third annual fundraiser for Child's Play, and it's always a fun event to keep tabs on. For those unfamiliar with the marathon, these guys play an utterly absurd amount of Mario, and the lengths that they go to depend on how much cash they bring in for the charity.

Take a look below at what they'll be playing for the forseeable future:

As of this writing, the guys are on World 8 of the original Super Mario Bros. and have raised over $8,000. As you can see, they have quite a bit of Goomba-stomping to do (and a lot more money to raise), so keep an eye on their progress and help out Child's Play if possible.
