Kristoffer's menstrual cup
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Kristoffer brings in a menstrual cup, and challenges Espen to identify it. Espen initially jokes that it is a penis extender, but is unable to guess it's true purpose, so Kristoffer earns 5 points.
