Now that we know Anderson Silva is capable of coming unhinged, Ultimate Fighting Championship (UFC) press conferences for the UFC 148: "Silva vs. Sonnen 2" pay-per-view (PPV) event, which goes down this Saturday night (July 7, 2012) at the MGM Grand Garden Arena in Las Vegas, Nevada, just got a lot more interesting.

Click here to see what happened the last time these two appeared before the media.

"The Spider" was joined by his arch nemesis earlier today (July 3) at Lagasse’s Stadium in The Palazzo Resort & Casino to help put the finishing touches on the promotional campaign designed to generate interest for their upcoming middleweight title fight.

As if we needed additional incentive to check this one out.

Nevertheless, Chael Sonnen will try to finish what he started way back at UFC 117 and exit "Sin City" with 185 pounds of gold around his waist. We'll know how this story ends in just a few short days.

See video of just their staredown, which forced UFC President Dana White (and his security team) to intervene, after the jump.
