Myrna Bellamy

Myrna Bellamy (generally referred to as "Mrs. Bellamy") is an elderly woman whom Homer helped with household chores. He and Marge were accused of murdering her. It is later learned, however, that Mrs. Bellamy is really a character created for a reality TV show.

History
Homer was sentenced to Community Service, and ended up delivering Meals on Wheels. When he went to Mrs. Bellamy's house, she was holding an axe when she greeted him, frightening Homer. It turned out that Mrs. Bellamy was just a kindly old woman starved for company, and the axe was for cutting Meals on Wheels steak. Homer helped Mrs. Bellamy with a couple of household chores, and this quickly escalated into his being at her house all the time. Marge went over to complain, and ended up helping Mrs. Bellamy as well. Soon Homer and Marge were, in effect, Mrs. Bellamy's personal servants. Both of them, but especially Marge, came to resent this, particularly when Mrs. Bellamy gave them degrading chores to do and generally treated them poorly.

After a card game with her friends, Mrs. Bellamy was apparently stabbed with scissors by a man with braces and a necklace was stolen from her house. Homer and Marge were the prime suspects. Everyone was suddenly wary of them, and soon during a Police raid on the Simpson home, the necklace was found with Maggie.

Marge and Homer were arrested, tried, convicted, and sentenced to death for Mrs. Bellamy's murder. Just before their execution date, Homer confessed to everything so that Marge could live. When Homer was strapped into the electric chair and the switch was pulled, it was revealed that all along they had been on Frame Up, a reality TV show. Mrs. Bellamy wasn't dead, and wasn't even an old woman; she was really actress in disguise.
