Ultimate Fighting Championship (UFC) today held its traditional pre-fight media press conference for this weekend's UFC 158: "St. Pierre vs. Diaz" pay-per-view (PPV) event, scheduled for March 16, 2013 at the Bell Centre in Montreal, Quebec, Canada.

And boy, it was a doozy.

Not only did we find out Nick Diaz was unsure if he would pass his post-fight drug test, we also learned that the winner of Carlos Condit vs. Johny Hendricks is guaranteed a shot at the 170-pound title in their next fight (more on that here). All while Georges St. Pierre and UFC President Dana White stood there, barely able to contain their disdain for the entire proceeding.

Diaz has a habit of bringing out the best in everybody.

With that in mind, White's media scrum should be nothing if not entertaining, as he sounds off on all the shenanigans from today's presser (and beyond) in the video above.
