Mary Hartman, Mary Hartman (nicknamed MH2 by fans) was a syndicated soap opera parody which ran from 1976 to 1978. The name came from the name of the main character and the fact that the writers said everything in soap operas was repeated twice. The show was very tongue-and-cheek, and dealt overtly with racy themes such as impotence and sexual perversio, and often had main characters killed off in odd ways such as bathtub electrocution, drowning in chicken soup, and impalement on an aluminum Christmas tree.

At the end of season 1, Mary Hartman had a nervous breakdown. The actress who played her left the show, and it was renamed Forever Fernwood (named after the fictional town the series took place in). There was also a talk show parody spin-off named Fernwood 2-Night.

Sounds like a funny show to me, but it was well before my time.
