The Biggest Career Comebacks from TV Actresses, Ranked

As Carol Kester, the wisecracking receptionist on The Bob Newhart Show (1972–1978), Marcia Wallace had a laugh that could fill a room. Her red hair and big personality made her a fan favorite. After the show ended, though, Hollywood didn’t quite know what to do with her.

Then came Springfield. From 1990 until her death in 2013, Marcia voiced Edna Krabappel, Bart’s weary fourth-grade teacher on The Simpsons. Her famous “Ha!” became iconic, and she won an Emmy in 1992. The show even retired Edna in her honor.
