TUF’s traditional coaches’ challenge went down last week and instead of ping pong or bowling or other athletic pursuits, the two coaches went machino a machino in an excavator obstacle course. They don’t just let anyone joyride around on heavy machinery and in order to play both Jon and Chael had to submit to breathalyzer tests. Watch as Chael Sonnen keeps his mouth conspicuously shut while Jones blows a negative. A slight change from his typical behavior when on twitter or FUEL TV, huh?

Bones knows.
