The legendary four way crimp, which took place at The Velvet Onion in Series Three.
The Velvet Onion is the name of the club that Bob Fossil owns in the third series of the Mighty Boosh. Vince Noir and Howard Moon perform there regularly under the stage name The Mighty Boosh. It also was the location for a performance by the group The Flighty Zeus, which challenged The Mighty Boosh to a crimp-off, resulting in the famous four way crimp, as seen in the episode "The Power of the Crimp".
