6. Bill Murray
He was the cast's first "new guy," which probably gave him that underdog's mean streak. More than anyone, he embodied SNL's this-could-be-you realness; he looked like a random Seventies burnout who happened to bluff his way to the stage — he made it seem like anyone could do it. Nobody's ever been so good at making audiences feel like they were funny, which in many ways is the essence of SNL.
Greatest hit: Nick the Lounge Singer, who treats every dismal gig like it could finally be his chance to shine. Whether he's in the Zephyr Room at Lake Minnehonka or the Powder Room on Meatloaf Mountain, he croons his heart out: "The first couple on the floor will also get their picture on the cover of next week's Breezy Point Lodge Bulletin, so, ladies and gentlemen — it's dancing time!"
