There is no line more iconic in reality television history than "You know what you did!" Watching the friendship between besties Lauren Conrad and Heidi Montag crumble right before your eyes proved to be a unique experience for reality TV. At the time, there was no show like The Hills and no reality TV show portraying such a simultaneously raw and fabricated story, predicated on both fact and tabloid. Paying attention to The Hills wasn't exactly the point, as MTV's best reality was more of a spectacle than anything else. But paying attention to The Hills also paid off at times. The Hills always busted out the best dramatics and theatrics, but it also managed to reveal the greatest inconsistencies and absurdities. There are certain things only diehard fans, those who paid attention to The Hills, will notice from past seasons and moments.
