A Tennessee woman was arrested by police - after she tricked her sister into thinking she had killed her husband.
"I was doing an April Fools' Joke," Susan Tammy Hudson, 52, told WKPT 19.
"I said, 'Helen, I shot my husband, I'm cleaning up the mess, let's go bury him in Blackwater'."
But the joke backfired when another relative ended up calling the local Kingsport police department.
Officers arrived at Mrs Hudson's home and took her into custody, according to Times News.
She was later released without charge and had nothing but praise for the local police: "The response was excellent," she told reporters.
