The Obsessivo-Compulsivo was a ship that Edward Van Helgen served on in 1675.
It had a crew of fifty men when it went in search for the wreck of The Rattling Phlegm. Two months into their voyage, many of thew crew were driven insane by a melody stuck in their heads. Many threw themselves into the sea in an attempt to escape it.
Only eight crew members survived.
- The melody that drove the men mad was the Monkey Island Theme Tune.
