Ya know, people like the Rock actually can refuse lines like that, having enough money already to do so. It actually is an option to say "fuck you, rewrite it, there is no way I am saying that, and I can go home." But he didn't, because he had been told that if he played ball he would be given a reward and he was stupid enough to think it would all be worth it. I am sure he was told he could be in line to be President one day and the fuckwit actually believed it. Freaking SONIC THE HEDGEHOG wanted to help lay a little groundwork with the line "Hey, is the Rock President yet?"
