A Nintendo fan earned himself a free 3DS player just for vowing to dress as the world's most famous plumber for a full month.

Gustavo Valdez made the solemn promise to Nintendo as part of a promotional contest asking fans what they would be willing to do for a free 3DS on Facebook. When Valdez pitched them his idea, Mario himself presented him with his free 3DS and some extra Mario costumes on the first day of his 30-day challenge.

Not much else has been made public about Valdez in terms of where he lives or what he does for a living. We're pulling for plumber from Kennett Square, Pennsylvania. It's the mushroom capital of the world.
