Museums preserve our history. They show us where we've been. They teach us things. They help us to learn our mistakes.

Speaking of mistakes, there's a penis museum in Iceland. Yup, a penis museum.

The curator ere thhas been collecting penises from every species for years, but his collection just isn't complete.

He's really jonesin' for a human penis and the documentary "The Final Member" follows his journey to get one.

Surprisingly, two people are lined up to donate their penises. An Icelander plans to donate his after his death. But an American, with a penis named Elmo, has decided to one-up the Icelander and donate his penis BEFORE his death.

Check out the trailer for "The Final Member" below!
