For those who might not know, "Pet Rock" was a famous (or infamous) product from the 1970s. It was essentially a smooth rock sold in a special carrying case, with instructions on how to care for it. The product was created by Gary Dahl in 1975 and became a cultural phenomenon, often symbolizing the simplicity and sometimes absurdity of consumer products.
