Well, I don't think he'd chimp out if he realized it didn't work. But even if he would, that begs the question: how could you prove to Chris that it isn't working?
Chris still believes the curse-ye-ha-me-ha works, for example.
Any idea when he last mentioned curses? The last example on the wiki is for Tito in 2010. I half expected him to curse trump. Does he think it works but doesn't use it because it's evil?
