I'm guessing "he busted his ass for years, toiling in ECW at best, then finally got to wrestle, for a title, in WWE, at MSG, and fans were chanting his name". Shit, how would you feel if you got to wrestle in your hometown (or at least somewhere close enough) after so long?
...Wait. Orton said he's challenging Triple H for the WWE Title at WrestleMania and they can't have any physical contact until then, otherwise Orton is canceling the match? Therefore, um, he won't get his WrestleMania title shot?
