She made her massive splash as Rachel Green in the tremendously popular sitcom "Friends." Men, women, children, and probably even animals all fell in love with her girl-next-door loveliness and her quickly imitated hairstyle. She was the ultimate girlfriend: sexy, funny, down to earth, and sweet. And she was very funny, possessing a comic timing and delivery that is, dare I say, Aniston-esque. It's no wonder those comic geniuses at "South Park" (Matt Stone and Trey Parker) cast her vocal talent as the kids' teacher during the hysterical rainforest episode. Who would mistake that voice, those nicely timed inflections?

With the release of her newest movie, "Love Happens," in which she plays a free-spirited, funky Seattle florist to Aaron Eckhart's suffering self-help guru, Aniston continues her on-screen appeal. No, she hasn't made her "Casablanca" quite yet (unless you count "Marley & Me" which, sorry, is quite charming). But she has appeared in, among other pictures: an underrated anti-romantic comedy; a poignantly funny, dark indie drama; a bona fide cult classic; and a movie opposite a leprechaun. And she did so with talent, charm and emotion. And sometimes with fantastic hair. But that's hard for her to avoid. With that, here are five of my favorite Aniston performances. Argue, dissect or agree. But please (as much as I love her ex's paramour) refrain from any Team Jolie business.
