Gary Ross Dahl. Pet Rock.
The success of Pet Rock has its origins in a joke. The future founder of the Society decided one day that it would be fun to have as “pet” … stones! He exploited this idea in 1975, and won a million dollars. These stones were sold in cartons with holes, and packaged as if they were sleeping in a cozy nest. In the manual, we explained how to take care of them, go for walks with them and how to treat them if she became ill or died. Since 2012, Pet Rock has become very popular again.
