We've talked about the uggos on SNL — but who was let go from the show that should have stayed, or who stayed on the show but never had his or her talents used well?

For instance — I like Casey Wilson, but she never got much to do on the show, so it's hard to tell if she would have been funny.

Michaela Watkins was fired after one season, but she was better than many of the women who'd joined the cast.

Laurie Metcalf may be the ultimate example: one episode and gone.
