Gary Dahl, who created one of the most incredible sales juggernauts of the 1970s, has died.

His product was the Pet Rock.  That's it, just a rock.  As a joke he marketed it as "the perfect pet.  No walking, no bathing, no feeding, no vet bills, simple."  He gussied it up with its own box/cage and marketed it in magazines and late night television shows.  His pet rocks were simply grey stones he bought at a lumber and building supply store.

Within one year he sold 1.5 million Pet Rocks and became a millionaire.  He was 78 at the time of his death.

Did you have one?
