It helps that they manage to make Nick and Eddie complete Bevis and Buttheads that barely manage to say an intelligent thing between. It not only makes them entertaining enough for the viewer to want to see more of them, but also shows sharp contrast between not only them and Simon, but Marshall at all. There's no doubt that the only reason Mars is entertaining them is because it doesn't crick his neck to talk to them.... XD
