mindblowingfactz:Gary Dahl, an advertising executive, created the Pet Rock in 1975. He took rocks from a Mexican beach, packaged them in a box with a booklet on “the care and training of your pet rock and sold over 1 million Pet Rocks for $4 each.While living in Los Gatos, California, he was sitting in a bar listening to friends complain about their pets. He joked that he had the perfect pet, a rock.This led to the idea of selling rocks to people as pets, complete with instructions. The instruction book was the real product, which was full of gags and puns. The 1975 fad only lasted about half a year, but that was enough to make Dahl a millionaire. -- source link
