The Icelandic Phallological Museum in Reykjavík is the world’s only museum devoted to the male genitalia. It contains over 280 specimens representing 93 different species of land and sea animals, including humans, and it was all collected by one person.

It started as a joke. In 1974, Sigurður Hjartarson was a 33-year old headmaster in a secondary school when a colleague gifted him the penis of a bull after hearing how Hjartarson had one as a boy. Soon, other teachers who worked in a nearby whaling station started bringing him whale penises, just to tease him. Eventually it gave him an idea that it might be interesting to collect specimens from more mammalian species.
