If you're on camera for a few weeks in front of millions of viewers, try to be as amiable as possible.
Tait, after just 2 episodes, is universally reviled after only a few minutes (!) of footage.
Diego Sanchez, a true threat to the 170 division, has few fans and is underrated because he's considered weird after the cameras highlighted his goofy antics. I don't even have to mention the negative following Southworth and Koschek have because of their treatment of Leben.
The moral is even if you're an asshole, it's only 6 weeks in front of the camera, so don't give the editors anything which they can use to portray you as the villain.
