Leah MacGrady

Leah (formerly Sara) MacGrady (also spelled McGrady) is Lakewood Elementary School's lunch lady. She enjoys bingo and is friends with Grandma Thora.

In the episode "The Great MacGrady," she has cancer and loses her hair from the chemotherapy. By "Prunella and the Haunted Locker," also a season 13 episode, her hair has grown back. Her replacement in "The Great MacGrady" is her nephew, Skip Bitterman. When she returns in that episode, Skip calls her Aunt Leah, instead of Sarah. This continues on throughout the series. "Leah" could be referencing one of the writers of the episode, Leah Ryan, which the episode was dedicated to. Also revealed in "The Great MacGrady," Mrs. MacGrady has a sister, Martha, who stayed with her after she was diagnosed with cancer.

In Arthur, It's Only Rock and Roll, she is the keyboardist for U Stink.

In the episode "Arthur Accused!" it is revealed that her first husband's name is Chester.
