Now, I know Ross and Rachel get all the attention when it comes to the Friends cast, but aren't Chandler and Monica really the staple to everything? In comparison, they're highly sensible, loving, and loyal to each other. That doesn't stop them from fighting or differing, in fact, it could be said that it amplifies how important they are to the rest of the group. These two are really the only real-life models to Joey, Ross, Rachel, and Phoebe for a working relationship with a friend. And since the cast of this show is almost always mixing and matching with each other at some point, the fact that Monica and Chandler work out so well is a real testament of what could be. So, you can keep your Ross and Rachel obsession, if you want. But there's better, funnier, more genuine things happening between the other couple.
