Lizzie Borden took an axe

And gave her mother forty whacks

When she saw what she had done

She gave her father forty-one

Lizzie Borden was an American woman who brutaly murdered her father and stepmother (Andrew Jackson Borden and Abby Durfee Gray Borden, Andrew's second wife) in Fall River, Massachusetts.
