11. Dana Carvey
Carvey was the greatest impersonations guy in SNL history — his impressions were usually darker and more compelling characters than the originals. His Ross Perot was way more than a parody of a politician — Carvey turned the character into an American archetype worthy of Randy Newman, sneering "Here's the deal, see" in the voice of every boss or principal you ever despised. When people try to imitate Johnny Carson or George H.W. Bush (or Lorne Michaels), they're usually just doing Carvey's impression.
Greatest hit: Perot behind the wheel, taking Phil Hartman's Admiral Stockdale for a final joyride. "That was world-class."
