During the 1930s, a genre of cruel jokes became popular known as "Little Audrey" jokes. The short jokes were usually pretty macabre, involving various fatal events happening to people. They also featured the catch phrase that Little Audrey "just laughed and laughed".
In rare cases the bad stuff happened to Little Audrey and then people laughed and laughed at her.
You can find some more info about Little Audrey (and more jokes) in B.A. Botkin's book The American People: Stories, Legends, Tales, Traditions, and Songs
A few of the jokes:
One day Little Audrey and her mother were driving along when all of a sudden the car door flew open and Little Audrey's mother fell out. Little Audrey just laughed and laughed, 'cause she knew all the time that her mother had on her light fall suit.
Little Audrey and her grandma were standing on their front porch watching the men pave their street. There was a cement mixer, a steam roller, and all kinds of things to watch. All of a sudden grandma saw a quarter out there right in the middle of the street. She dashed right out to get it, but just as she picked it up along came that old steam roller and rolled her out flatter than a sheet of theme paper. Little Audrey just laughed and laughed, 'cause she knew all the time it was only a dime.
Little Audrey was playing with matches. Mama said, "Ummm, you better not do that." But Little Audrey was awful hard-headed; she kept right on playing with matches, and after a while she set the house on fire, and it burned right down to the ground. Mama and Little Audrey were looking at the ashes, and mama said, "Uh huh, I told you so! Now, young lady, just wait until your papa comes home. You certainly will catch it!" Little Audrey just laughed and laughed. She knew all the time that papa had come home an hour early and had gone to bed to take a nap.
Little Audrey was standing on the corner just a-crying and a-crying, when along comes a cop, who said, "Little Audrey, why are you crying?" And Little Audrey said, "Oh, I've lost my papa!" The cop said, "Why Little Audrey, I wouldn't cry about that. There's your papa right across the street leaning against that bank building." Little Audrey was overjoyed; without even looking at the traffic she started across the street. Along came a big two-ton truck that ran over Little Audrey and killed her dead. The cop just laughed and laughed. He knew all the time that that was not Little Audrey's papa leaning against the bank building.
