What happened

The committee boxed 800 stones from the Danube bank and sold them as Pet Slop, each with a leaflet on training. They did not sell. They were given away as door prizes instead, and 64 were returned, making them nearly as unpopular as the Blechkopf, which that year was won by a rock.

Elsewhere in 1975

Gary Dahl's Pet Rock, an ordinary stone sold in a cardboard box with a care manual, becomes a Christmas craze in the US.
