14. Kristen Wiig
One of a kind. You could argue she ran too many characters into the ground — Gilly again? — but she had a knack for high-strung basket cases, from her flirting expert Rebecca Larue ("I'm just really hearing you") to "Cougar Den" host Toni Ward. When Lana Del Rey showed up, she seemed like a real-life Kristen Wiig character. Wiig got the most sentimental send-off of any cast member ever, complete with Mick Jagger singing "She's a Rainbow," and she earned it.
Greatest hit: Mindy Grayson, a washed-out theater queen who still dreams of her Broadway glory in smash failures like And Sarah Made a Sound ("the story of a mute girl who desperately wanted to say the word 'jazz' ") and Sassy Slacks of 1963.
