Watch a New Clip from the Penis Museum Documentary, The Final Member

"It started as a joke," Siggi says of the origins of the world's only penis museum. The Icelandic Phallological Museum, which houses four decades worth of mammalian members, from a petite field mouse to the colossal sperm whale, is the subject of a new documentary, The Final Member. The film tells the story of the museum's quest to obtain a human penis to complete it's collection.

In a new clip from the upcoming film, the founder and curator discusses how the museum came to be. (Apparently you give a man a bull penis and he runs with the idea.)

The documentary hits select theaters of April 18th. Watch the trailer below.
