Joke? What the hell are you talking about? Was it a joke that Emerson smoked a solid LW in Manny? or how about getting screwed over against Gray Maynard? These were no flukes. As Javier Vazquez about Rotten Rob, he'll tell you that he (Javier) was lucky that the judges gave him a gift. Keita Nakamura definitely doesn't suck, dude's a really good fighter, and Rob dominated him.
But, of course, most think this is some joke. It's no joke. The only joke is the decision in the Hill vs Emerson TUF 5 fight.
