Poll: Greatest SNL cast member ever (final)?

Saturday Night Live (1975) is beginning its 40th season at the end of September. This is final poll in a group of a group of polls to determine the greatest SNL cast member ever. Each poll included cast members from a five-year time period (if a cast member's tenure ran over two or more periods I put them in the one with the most years they appeared in). The top three of each of these polls are now going against each other in this poll to determine the single greatest SNL cast member ever (full repertory members only, no featured players). Who is the greatest SNL cast member ever (based on their performances on SNL only)?
