'Gossip Girl'... in 'The O.C.'?

Exhibit A: Blair Waldorf = Summer Roberts

Rich, popular and totally bitchy, Blair and Summer are the head Heathers of their respective coastal cliques.

Because they're evil, they have shiny brunette hair. And because the actresses playing them (Leighton Meister and Rachel Bilson) are way more adorable and charming and interesting than the good girl characters, somehow Blair and Summer end up being infinitely more sympathetic than they ought to be.
