Remember that guy who purposely stung himself with a wasp that can allegedly kill a cow? Well, two guys may have one-upped him by running on a treadmill covered in thumbtacks. God, that sentence made me cringe just writing it.

WheresMyChallenge is a group of dudes named Paul, Harry, Matt, and Lewis who do stupid stuff—or, in their words, "take on challenges and try our best to beat them or fail in style." After their video featuring them running on a treadmill of Legos went viral, they decided, hey—let's fuck up our feet even more in the name of social media engagement!

Shouldn't really have to say this, but don't watch this video if you're squeamish. Or just don't watch it at all.
